Can Layers be given RELATIVE, rather than ABSOLUTE position

I'm having no luck finding an answer to this in HELP. I place
the layer's anchor in a table, then position the layer. If I
subsequently add (or remove) any lines above the anchor, everything
on the page moves down (or up), but the layer stays where it was,
relative to the page, not the anchor.
If there are several layers on the page this means a wholeot
of repositioning every time I do an edit up-page.
Any advice?

This may help you understand positioning a bit -
There are 4 different types of positioning:
Absolute
Relative
Fixed
Static
Here is a brief explanation of each kind of positioning (with
regard to
placement of elements on the page only)....
Position:absolute (or A/P elements)
This does several things -
1. It 'removes' the element from the flow of the code on
the page so that
it can no longer influence the size or position of any other
page element
(except for those contained within it, of course).
2. The absolutely positioned element takes its position from
the position of
its closest PARENT *positioned* element - in the
absence of any explicitly
positioned parent, this will default to the <body> tag,
which is always
positioned
at 0,0 in the browser viewport.
This means that it doesn't matter where in the HTML code the
layer's code
appears (between <body> and </body>), its
location on the screen will not
change (this assumes that you have not positioned the A/P
element within
a table or another A/P element, of course).
Furthermore, the space in
which
this element would have appeared were it not positioned
is not preserved
on the screen. In other words, absolutely positioned elements
don't take
up any space on the page. In fact, they FLOAT over the page.
Position:relative (or R/P elements)
In contrast to absolute positioning, a relatively positioned
page element is
*not* removed from the flow of the code on the page, so
it will use the
spot
where it would have appeared based on its position in
the code as its
zero point reference. If you then supply top, right,
bottom, or left
positions
to the style for this element, those values will be
used as offsets from
its
zero point.
This means that it DOES matter where in the code the
relatively positioned
element appears (, as it will be positioned in that location
(factoring in
the offsets) on the screen (this is true for any placement in
the code).
Furthermore, the space where this element would have
appeared is
preserved in the display, and can therefore affect the
placement of
succeeding elements. This means that the taller a relatively
positioned element is, the more space it forces on the page.
Position:static
As with relative position, static positions also "go with
the flow". An
element with a static position cannot have values for
offsets (top, right,
left, bottom) or if it has them, they will be ignored. Unless
explicitly
positioned, all div elements default to static positioning.
Position:fixed
A page element with this style will not scroll as the page
content scrolls.
Support for this in elements other than page backgrounds is
quirky
There are several other things you need to know:
1. ANY page element can be positioned - paragraphs, tables,
images, lists,
etc.
2. The <div> tag is a BLOCK level tag. This means that
if it is not
positioned or explicitly styled otherwise, a) it will always
begin on a new
line on the screen, and b) it will always force content to a
new line below
it, and c) it will always take up the entire width of its
container (i.e.,
width:100%).
3. The placement of A/P elements *can* affect the BEHAVIOR of
other
elements
on the page. For example, a 'layer' placed over a hyperlink
will mask that
hyperlink.
You can see a good example of the essential difference
between absolute and
relative positioning here -
http://www.great-web-sights.com/g_layersdemo.asp
You can see a good demonstration of why using layers for a
page layout tool
is dangerous here -
http://www.great-web-sights.com/g_layer-overlap.asp
Based on this, a static div (no longer a 'layer') would be
what you want.

  • How can copied calculations be made relative rather than absolute?

    Frequently I like to copy a recurring item from a previous entry, change the date and assume all will be well. But Numbers 3.2.2 also copies the calculations as absolute rather than relative. That is a calculation of previous balance plus a credit minus a debit is referencing the copied balance, credit and debits rather the balance, credit and debits in the new location, thus throwing the calculations off.
    Supplementary question:
    Is there a fast way to correct the wrong calculations once made? A fast way to restore an orderly sequence one row referencing the previous row's balance and the current row's credits and debits?

    Hi Wanapitei
    Have you tried this?
    Click on a "lozenge" (A2 in this example) to see the contextual menu.
    Clicking on Preserve Row or Preserve Column will turn on (or turn off) the $ sign in the formula. That toggles between Absolute and Relative references.
    Regards,
    Ian.

  • Navigation Wizard waypoint relative rather than absolute?

    Is there a reason why Wizard.onNavigateTo only checks agains the immediate parent waypoint? This limits the wizard from working across multiple waypoint levels and doesn't work with nested waypoints.
    1. Create a wizard with a waypoint called foo.bar containing several children
    e.g.
    <wizard:Wizard id="myWizard" waypoint="foo.bar">
            <mx:Array>
                <mx:String>foo.bar.step1</mx:String>
                <mx:String>foo.bar.step2</mx:String>
                <mx:String>foo.bar.step3</mx:String>
            </mx:Array>
    </wizard:Wizard>
    2. Navigating to a destination within foo.bar using the wizard
    e.g. foo.bar.step2
    in the wizard onNavigateTo it checks that the wizard waypoint equals "bar" instead of "foo.bar" and doesn't update.
    Would it be more flexible to check if the target destination is within the wizard and update the currentDestination accordingly? If the target destination is not within the wizard then perhaps the wizard resets currentDestination to null? A better solution would be to use the wizard's waypoint to determine if the currentDestination is reset when a navigateTo event occurs - if the destination is outside the 'scope' of the wizard waypoint (i.e. not a decendant) then set to null, otherwise leave wizard state as is.

    Is there any way I can upgrade to version 6 rather than IOS7?

    No.  iTunes and over the air updates work by detecting your hardware, and then only offer the latest available version of iOS compatible with that hardware.  Older releases will simply not be available for hardware.

  • Can I use album artist rather than Artist on my iPod160?

    The Artist selection on the iPod has its problems as "Album Artist" is not always the same as "Artist". I know I can correct the Cover Flow problems with Artist View by use of the Sort Artist option but I do have a few questions.
    I would rather display the Album Artist rather than Artist. Is this possible? I can do it in ITunes but cannot seem to do it on the iPod itself.
    Also, is it possible to do mass changes on Sort Artist rather than hit "next", paste the change, etc. Everything I try to mass change, Sort Artist is not an option.

    Hi,
    Unfortunately, the 'album artist' field is ignored on the iPod (I hope it one day will be 'solved'). If you mark albums with multiple artists as 'compilation', the album artist in iPod coverflow is automatically set to 'various artists'. And I haven't found a way to mass-edit the sort fields either

  • Can iWeb publish with JPEGS rather than PNG?

    Is there any way to make iWeb use only jpegs rather than PNG files when publishing? Also, I think a picture quality slider would be helpfull for compression and site size management... thanks

    You can minimize the chances of iWeb converting your jpgs into PNGs if you pay attention to the following things...
    1. Scale your jpgs to the resolution they are to be used...don't let iWeb do the scaling if possible (like dropping a photo in and then adjusting the size handles). Target your resolution and then drop the photo in and select "Use Original Size" in the Inspector Shape tab.
    2. Do not apply effects to your jpgs....if you do, iWeb will automatically convert to PNG and the file size will be even bigger! These effects include drop shadows, rotation, frames, opacity changes, etc.
    3. Be aware that in some templates, dropping a photo into iWeb automatically applies frames, drop shadows, and/or reflections. You can deselect these enhancements in the Inspector panel after dropping the photos in. If you don't, iWeb will convert to PNG.
    4. Do not use the "Use image as background" option. Better to drag an exactly sized jpg photo into iWeb and push it to the very back layer than to use this option.
    You are right, iWeb or at least iPhoto needs to have some sort of user control over jpg compression. I use another app for this purpose called "Downsize". On the plus side, it also lets me apply shadows and frames to photos and saves the finished image with effects and all as a jpg.

  • Can you purchase photoshop permanently rather than yearly?

    I want to buy photoshop, but I don't want to pay for creative cloud every month/year, so is there a way that I can purchase photoshop and pay 1 flat fee?

    I'm not trying to influence you one way or another.  Just some things to think about:
    Given that Photoshop CS6 is about $700 (Extended is $1000), you may want to think about the $9.99 Photographer's deal as a comparison...
    Creative Cloud free trial & plans : Adobe Creative Cloud
    If you plunk down $700 now, you get an already outdated version of Photoshop.  Photoshop CS6 works, but there actually are some very good things that have been implemented in Photoshop CC.  And Photoshop CC is more efficient (outside of a few folks who are having problems with it).
    If you subscribe to that Creative Cloud deal I mentioned, you plunk down $120 for the first year.  You could save the additional $580 and use it to pay for the subscription in the future, in which case you'll be able to use Photoshop CC for more than 5 years at the current rate.  Or you could invest it in ADBE stock.
    The term "Perpetual License" is kind of a misnomer...  You're not really guaranteed to be able to run it forever into the future on the latest operating system release of the day.  How long is your computer going to last?  Will you decide to upgrade to a new version of your OS under which Photoshop CS6 will not run?  Will Adobe one day take their CS6 activation servers offline?  We can't know.  If Adobe were to lose its business it's possible you won't be able to run any version of Photoshop beyond the day that happens.  No one can predict the future, but I'm just pointing out that you're at the mercy of Adobe's online activation process either way.
    If you choose to get a computer of the other platform (e.g., Mac vs. PC), your CC license allows you to use Photoshop in both places.  With Photoshop CS6, though Adobe does currently offer a "crossgrade", you can only use it on one platform or the other exclusively.
    If Adobe had continued to offer new version releases every couple of years, would you likely have upgraded at some time in the future?  If you've had an older version already, how many versions did you skip between upgrades?
    Some folks simply feel negatively about subscribing vs. buying a license to use, and I fully respect that.   I'm just giving some things to think about.

  • I synced with iMac itunes and got many more contacts than I want on the iPhone. How can I delete multiple contacts rather than having to do so one at a time?

    I synced my iPhone with itunes and iMac and got many more contacts than I wanted on my iPhone. How can I delete quite a few of them at one time as opposed to deleting one at a time?

    iTunes does not handle the import of photos/videos from the iPhone's Camera Roll.
    If this is not the computer you sync your iPhone with, you should have been provided a warning message that your iPhone is associated with an iTunes library on another computer and when trying to transfer any iTunes content from a different computer, a warning message is provided indicating that all iTunes content on the iPhone will be erased first.
    When connecting an iPhone to iTunes on another computer, none of the options under the various tabs for the iPhone sync preferences with iTunes are selected automatically. This means you had to select Sync Contacts under the Info tab for your iPhone sync preferences with iTunes on your wife's computer.
    Assuming you are syncing contacts with a supported address book app on your computer, connect your iPhone to Tunes on your computer and without syncing, under the Info tab for your iPhone sync preferences below the Advanced section, select Contacts for replace info on this iPhone followed by a sync.
    For importing photos/videos from the Camera Roll which can be done with a computer that is not used for syncing the iPhone since syncing with iTunes is not involved.

  • The latest version of Firefox has a compatability problem with the Reget download manger which means I can only download zipped files rather than large MOV or MKV files as could previously be done. Is there a solution to this issue?

    As per above the Reget add on is now not compatible with Firefox's latest version. Is this something which Firefox is looking into? Is there a work around or is this up to Reget to remedy?

    I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
    When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
    At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
    I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

  • Can an EDQ job preserve rather than overwrite its previous outputs

    We have a job running on a scheduled basis that outputs data quality issues to a spreadsheet.
    We would like to keep a history of specific error details (e.g. which records had which data quality issues) over time (i.e. more details than the simple measures that can be published to the Dashboard for seeing trends over time).
    I believe we could do this kind of thing using an export to an external database table (or even a file in the EDQ server's landing area) using the 'Append to current data' option however is that a recommended way to go or is there any alternative e.g. is it possible for the job to write to
    (a) a spreadsheet/file with a different name each time it runs (e.g. suffixed with the run timestamp) or
    (b) an EDQ staged data area without deleting what was previously in the table (we could include a run timestamp column to distinguish the runs).
    Thanks, Nik

    Thanks for the update Mike - and for reminding me of that option (I hadn't been using run labels to now due to the fact that these are not compatible with Result Book exports to spreadsheets).
    I guess in that latter case we would have to use the command line utility runopsjob in conjunction with a scheduled script (run at the operating system level) that changes the -runlabel argument passed to it.
    Thanks, Nik

  • Can I install an earlier version of Bootcamp on my new Macbook Pro so that I can dual boot to XP rather than Windows 7??

    I have a new MacBook Pro and would like to dual boot ot XP. Is this possible using the Bootcamp version that comes with it? I wonder whether Apple have XP drivers for the new MacBook or if they have only developed those for Windows 7? Thanks in advance!

    Just install XP into a Virtual Machine. Like VMware Fusion, Parallels or Virtual Box.
    Then you can run both OS X & XP at the same time. No need to dual boot with XP as it doesn't use that many rsources and runs fine in a VM.

  • In imovie how do I seperate all my videos from the photos from iphoto? I have thousands of photos so finding the odd video here or there is like finding a needle in a haystack! Is there a way I can simply import the videos rather than all the photos

    Imovies - how do I seperate the videos from the photos. My library has bundled them all together from iphoto

    One way I was able to do this, was to make a Smart Album in iPhoto, with the rule of showing just the movie files.  This will work, once you know what format the movie files are in.
    In iPhoto, select one of your movies, and right click it.  Look for the option: "Reveal in Finder" or "Show in Finder" (this depends on the version of iPhoto).
    Once you see the file, look for the three letters AFTER the period.  Like this:
    .mov (QuickTime movie)
    .avi  (Uncompressed Windows Video)
    .mpg (MPEG video)
    Back in iPhoto, when you make your Smart Album, set it up like this:
    Once you have it set like this, press RETURN (or click "Ok").
    What you'll see is all the videos that have that file extension (.mov, .avi, .mpg, etc.) listed.  Now the nice thing is this:  Every new movie you add to iPhoto will automatically get listed here, regardless of where in iPhoto they live!
    Integration with iMovie:
    By making this album in iPhoto, when you get to iMovie, you'll be able to see the movies when you select your Videos Smart Album.
    I hope this helps you out.  They have iPhoto and iMovie workshops at Apple Stores that cover this too.  They're free, and you can learn a lot.
    Sincerely,
    Brian K. James
