Force vertical scroll bar

Question

Hi all,
I would like to force a vertical scroll bar on all of my pages to keep the page from appearing to shift on some pages (pages long enough for scoll bars vs pages not long enough to need scroll bar). On my site I notice it in IE8 and FF3.
I know this has been discussed before but I am not able to find it.
Here is my code currently in my style.css concerning HTML and body elements
html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6 {
margin: 0;
padding: 0;
border: 0;
outline: 0;
html {
font-family: Arial, Helvetica, sans-serif;
font-size:  76%;
height: 100%;
body {
color: #000;
margin: 0 0 0 0; /* Sets the margin properties for an element using shorthand notation (top, right, bottom, left) */
padding: 0 0 0 0; /* Sets the padding properties for an element using shorthand notation (top, right, bottom, left) */
text-align: center; /* Centers the page content container in IE 5 browsers. */
background: #2D4262;
  How would  I accomplish this?
Thanks
Chris

Thanks for responding,
I tried both ways..I do not know CSS very well so I probably did it incorrectly.. Heres what happens when I tried both ways.
My background goes away if I add Michaels suggestion:
To see if I did it correctly here is what I had
html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6 {
margin: 0;
padding: 0;
border: 0;
outline: 0;
html {
font-family: Arial, Helvetica, sans-serif;
font-size:  76%;
margin-bottom:.01px;
min-height:100.2%;
And if I tried to add Murrays suggestion, nothing happened
To see if I did it correctly, here is what I had
html, :root { overflow-y:scroll; }
html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6 {
margin: 0;
padding: 0;
border: 0;
outline: 0;}
html {
font-family: Arial, Helvetica, sans-serif;
font-size:  76%;
height: 100%;
Again, I am probably not doing it correctly....
Thanks
