RH-generated WebHelp doesn't display some CSS styles

Question

I've worked with RH for a while, including creating other WebHelp projects in RH that have been deployed without any problem. On my current RH9 project, however, some of the CSS styles are not being applied after the project output is moved to a network directory. When I open the project output on my Desktop, the styles all render correctly.
The styles in question aren't especially unusual:
DIV.text {
          width: 640px;
          padding-left: 25px;
          padding-right: 25px;
          padding-bottom: 25px;
          margin-left: auto;
          margin-right: auto;
          background-color: #EDEBDE;
P.footer {
          text-align: center;
          font-size: 8pt;
          line-height: 25%;
          color: #A13619;
The kicker is that some of the styles ARE being applied (e.g., background image), while the 2 styles above are NOT being applied.
Some of the things I've already tried include:
- creating a new copy of the CSS file
- making sure the correct stylesheet is referenced in the HTML files
- making sure the correct stylesheet is referenced in the MasterPage
- making sure the correct CSS type is specified in the HTML files
- adding "!important" to the styles that aren't being applied
Has anyone seen / resolved issues like this before?
Thanks!

Solution:
My supervisor and I huddled on the problem and eventually found these discussions:

I opened the IE Tools > Developer Tools panel, and used the Browser Mode settings to check the variations (IE7, IE8, and IE8 Compatibility). IE8 displayed all DIVs correctly, while the other two apparently severed the CSS file from the HTM file.
I had to do a mass find/replace, pasting another meta tag below the RH generated compatibility check:
<meta http-equiv="X-UA-Compatible" content="IE=8" />
And there was much rejoicing.
As an aside, the new meta tag did not work when I tried to apply it to the Master Page....which makes sense, I guess.
