Equal Height Technique

One of the somewhat frustrating properties of CSS is the fact that elements only stretch vertically as far as they need to. So how can we make all columns appear to be the same height? Several techniques was introduced to solve this issue.

  • Faux Columns– The simple secret is to use a vertically tiled background image to create the illusion of colored columns.
  • Equal Height Columns – revisited– A method to make all columns appear to be the same height but without the need for faux column style background images.
  • Equal height boxes with CSS– The trick is to use the CSS properties display:table, display:table-row and display:table-cell to make containers (in this case div elements) behave like table cells. The basic XHTML structure looks like this:
        <div class="equal">    <div class="row">    <div class="one"></div>   
     <div class="two"></div>   
      <div class="three"></div>    </div>    </div>    

    Here is the CSS used to make this structure behave like a table:

         .equal {            display:table;    }    .row {            display:table-row;    }   
     .row div {     
           display:table-cell;    }    




Turning A List Into A Navigation bar

Why use a list? Because a navigation bar, or menu, is a list of links. The most semantic way of marking up a list of links is to use a list element. Using a list also has the benefit of providing structure even if CSS is disabled.




Making Headlines With CSS

Headers in Web pages–marked up with h1, h2, h3, h4, h5, or h6 elements–help the reader determine the purpose of sections in content. If your header is visually stimulating, the odds are better that the section will capture your reader’s eye.

  • Typography for Headlines– Improve the typography in your headlines by being more creative, give them more ‘pop’, that sort of thing.

Various Link Techniques

  • Showing Hyperlink Cues with CSS– The CSS Guy shows us how to get the little icons next to hyperlinks that signify if that link will take you offsite, open a popup, or link to a file (as opposed to another html page). Here’s how to do it in a way that’s supported in IE7, Firefox, and Safari.
  • The ways to style visited Links– CSS offers various possibilities to make links more usable and preserve text readability at the same time. We need to differentiate visited and unvisited links, but we must keep text scannable and readable.
