Position: fixed CSS templates

About a design with a fixed header, fixed left column, and scrolling right column, I thought I’d renew my take on simulating frames with CSS (The original article is still good for background information, so I still recommend reading it).

Position: fixed CSS templates

The idea is this: Instead of specifying what parts of the page should scroll, we can specify what parts should stay fixed when scrolling. This makes it easier to deal with several fixed parts of the same layout, but also allows us do to things frames cannot do.

So what’s the trick? Well, position: fixed does exactly what we want. It works just like position:absolute, but it stays still when the page is scrolled. So it’s really just a matter of making sure things don’t overlap.

  • Demo: Fixed top, fixed left, scrolling right
  • Demo: Fixed top, scrolling bottom
  • Demo: Fixed left, scrolling right

Try resizing the page, and see how the scrolling works. The templates have been tested in: Fx 3.5, IE8, IE7, IE6 (see note below), Opera 10, Safari 4; all on Windows. Let me know if you can test it on more browsers, or find bugs.

You’re of course free to use this templates as you see fit, with or without a link back, commercially or not. Consider it public domain.

Fixes for IE6

As I’ve said, these designs don’t act the same in IE6. Instead of some parts being fixed, the whole page scrolls in IE6. The good thing about this is that IE6 users won’t see that your site is “broken”, they will just get another design. And as the number of IE6 users goes towards zero, your design will be more and more consistent :). The fallback is very simple, IE6 gets position: absolute instead of fixed, using the !important hack (you should probably use conditional comments instead).

Hope these templates are useful for some of you!

excellently suited to give special instructions meant only for IE. They are supported from IE 5 onwards.

Conditional comments work as follows:

<!--[if IE 6]>
Special instructions for IE 6 here
  1. Their basic structure is the same as an HTML comment (<!-- -->). Therefore all other browsers will see them as normal comments and will ignore them entirely.
  2. IE, though, has been programmed to recognize the special <!--[if IE]> syntax, resolves the if and parses the content of the conditional comment as if it were normal page content.
  3. Since conditional comments use the HTML comment structure, they can only be included in HTML files, and not in CSS files. I'd have preferred to put the special styles in the CSS file, but that's impossible. You can also put an entire new <link> tag in the conditional comment referring to an extra style sheet.


Below I added a lot of conditional comments that print out messages according to your IE version.

Note however, that if you use multiple Explorers on one computer, the conditional comments will render as if all these Explorer versions are the highest Explorer version available on your machine (usually Explorer 6.0).


Below are a few conditional comments that reveal the IE version you're using.

According to the conditional comment this is not IE


The syntax I use is:

<p class="accent">
<!--[if IE]>
According to the conditional comment this is IE<br />
<!--[if IE 6]>
According to the conditional comment this is IE 6<br />
<!--[if IE 7]>
According to the conditional comment this is IE 7<br />
<!--[if IE 8]>
According to the conditional comment this is IE 8<br />
<!--[if IE 9]>
According to the conditional comment this is IE 9<br />
<!--[if gte IE 8]>
According to the conditional comment this is IE 8 or higher<br />
<!--[if lt IE 9]>
According to the conditional comment this is IE lower than 9<br />
<!--[if lte IE 7]>
According to the conditional comment this is IE lower or equal to 7<br />
<!--[if gt IE 6]>
According to the conditional comment this is IE greater than 6<br />
<!--[if !IE]> -->
According to the conditional comment this is not IE<br />
<!-- <![endif]-->

Note the special syntax:

  • gt: greater than
  • lte: less than or equal to

Also note the last one. It has a different syntax, and its contents are shown in all browsers that are not IE:

<!--[if !IE]> -->

CSS hack?

Are conditional comments CSS hacks? Strictly speaking, yes, since they can serve to give special style instructions to some browsers. However, they do not rely on one browser bug to solve another one, as all true CSS hacks do. Besides, they can be used for more than CSS hacks only (though that rarely happens).

Since conditional comments are not based on a browser hack but on a deliberate feature I believe they are safe to use. Sure, other browsers could implement conditional comments, too (though as yet none have done so), but they're unlikely to react to the specific query <!--[if IE]>.

I use conditional comments, though sparingly. First I see if I can find a real CSS solution to an Explorer Windows problem. If I can't, though, I don't hesitate to use them.

Comment tag

A reader told me IE8 and below also support the (non-standard)<comment> tag.

<p>This is <comment>not</comment> IE.</p>

This is not IE.

This tag might be a replacement for the !IE conditional comment, but only if you target IE8 and below.
