CSS Frequently Asked Questions


 

Design:

 

Q. 

I know how to
center tables in an HTML file regardless of the screen resolution of the
user but is there a way to center the layers (again regardless of the user
screen resolution)?

A. 

You will want to
position a layer using CSS and want the positioning to be in the middle of
the screen regardless of screen size. You can do that giving percentages
instead of pixels. Here is a sample code:

<HTML>
<HEAD>

<STYLE TYPE="TEXT/CSS">
<!–
div.test {position:absolute; top: 50%;right: 50%}
–>
</STYLE>
</HEAD>

<BODY BGCOLOR="#FFFFFF">

<DIV class="test">Test</DIV>

</BODY>
</HTML>
 

Hyperlinks:

 

Q. 

Is it possible to have 2
different Visited Link colors for links on different parts of a page, e.g. a
navigation bar different from the content?

A. 

Yes, it is possible to do this
with help of classes. Basically, you have to give class names (e.g. <A HREF="file.html"
class="content">Link Text</A>) to all your links. The links in the content
section should have class="content" and the links in the navigation bar
section should have class="nav". Then add these lines to your STYLE’s:

a.nav:visited {color: red;}
a.content:visited {color: green;}

Basically this ensures that the anchors with the nav class that are visited
will have a color of red and likewise for the content. You could also change
fonts and actually do everything that stylesheets allow.

If you have many links in your content section, make life easier for
yourself: Just add class="nav" to the navigation bar links and these two
lines, instead of the two above to the styles.

a.nav:visited {color: red;}
a:visited {color: green;}

This way ALL your links’ color will be green EXCEPT for those who are tagged
as nav.
