Styling Code, Part 1
However, all those happen to the same selector, , which has no real separated attributes.
Therefore, pseudo classes act as those attribute separations. Here are examples of
how they can be styled, with commenting to explain:
• a:link {color: #990000; text-decoration:none;} /* can use #383, unvisited link is a
maroon color, no underline. Note: link must come before hover, visited, and focus
*/
• a:hover {font-size:120%; color: #000000;} /* can use #000, mouseover link
makes text bigger. Note: hover must come after link and before visited and focus
*/
• a:visited, a:focus {color: #666666;} /* can use #666, visited link is a medium
gray. Note: visited and focus must come after link and hover. */
CS Classes and ID
If you want a property to work throughout a site, you can set it as a class or id, like .red
{color:red;} turns any text red you use it as a class for.
If you want to affect only a specific selector, such as all text in a specific table cell, you
would list the selector then class or id: td.red {color:red;} This will be covered in more
detail in a later chapter about external style sheets.
Colors for Styling
We haven’t discussed the use of color in styling, which bears a closer look. One thing
every web author should get is a link to the web-safe HEX colors – just plug that into a
search engine and you’ll get plenty of examples.
Web-safe colors are colors used in designing web pages, and the methods for describing
and specifying those colors. These colors were chosen specifically because they matched
the palettes selected by the then leading browser applications. However, as devices have
16-bit to 24-bit color, web-safe colors are no longer required. Better results are obtained
by providing an image with a larger range of colors and allowing the browser to quantize
the color space if needed.
Authors of web pages have a variety of options available for specifying colors for elements
of web documents. Colors may be specified as an RGB triplet in hexadecimal format
(a hex triplet); they may also be specified according to their common English names
in some cases. Often a color tool or other graphics software is used to generate color values.
Professionally, HEX color expression seems to be common and using names like red,
green, and blue is not.
