Updating dates with CSS?

[Titties]

Hi

I am currently making a website using CSS and HTML
I have made a vertical left-aligned menu, where i wish to put a "last updated: date"
It is easy enough, but when i have multiple sites, I have to change the date manually on all of the sites.

Can I somehow enter the date in the stylesheet, so when i change the date in the stylesheet, it changes on all html files?

Thank you

No.

That's not what CSS is for.

Ok, thx

But is there any other way. For example loading an external file, so i just have to change that file?
I have tried with an iframe, but it ruins the design.. unless i can make the background see through/0% oppacity?

You could use... Frames.. (flinches) The problem with frames is, that if you go to another site that uses frames from your site, the frames in your page will be stuck in the next page. Now, there's a certain way to avoid this, I'm just not sure how...

The ideal way to do this is via server-side scripting. However, you can also do:

<script type="text/javascript">
  document.write("Document last modified: " + document.lastModified);
</script>

But you still have to add it to every page.

Yes, but it's not necessary to update each page.

Right.. I knew that.. lol

Thank you guys

I solved it myself with the use of an iFrame including and external file I called date.html, so now i just have to change the date.html.. but if you say one might encounter errors with frames, i will certainly try to use somethings else..

but i am not sure that I understand the code Twey so kindly provided:

<script type="text/javascript">
  document.write("Document last modified: " + document.lastModified);
</script>

So i just implement this on all the html sites the same place, like this (for example):

<script type="text/javascript">
  document.write("Document last modified: 1st of september 2008 " + document.lastModified);
</script>

And then just change it on one of the html files and then it auto updates on the other HTMLs?

Did I get that right?

No

You'd put the code in verbatim, and it would automatically display the last-modified time of each page. No need to worry about updating it.
