How do you show which page you’re on (in a menu)?
If PHP is not available to you, you could use the cascade. Put an id in your body tags and an id in each of your ‘a’ tags for the links.
Let’s say on page one you have this:
CSS
<body id="page1">
….
<a id="page1link" href="page1.htm">page one</a>
…
</body>
In your CSS, [...]
How do I move the list bullet to the left/right?
CSS1 has no properties for setting margins or padding around the bullet of a list item and in most cases the position of the bullet is browser-dependent. This is especially true since most browsers disagreed on whether a bullet is found within the margin or padding [...]
Can you use someone else’s Style Sheet without permission?
This is a somewhat fuzzy issue. As with HTML tags, style sheet information is given using a special language syntax. Use of the language is not copyrighted, and the syntax itself does not convey any content – only rendering information.
It is not a great idea to [...]
What’s the difference between ‘class’ and ‘id’?
As a person, you may have an ID card – a passport, a driving license or whatever – which identifies you as a unique individual. It’s the same with CSS. If you want to apply style to one element use ‘id’ (e.g.
<div id="myid">
). In the stylesheet, you identify an [...]
Why can @import be at the top only?
A style sheet that is imported into another one has a lower ranking in the cascading order: the importing style sheet overrides the imported one. Programmers may recognize this as the same model as in Java, Modula, Object-Pascal, Oberon and other modular programming languages.
However, there is a competing [...]
Must I quote property values?
Generally no. However, values containing white spaces, e.g. font-family names should be quoted as whitespaces surrounding the font name are ignored and whitespaces inside the font name are converted to a single space, thus font names made up of more than one word (e.g.) ‘Times New Roman’ are interpreted as three [...]
What is the percentage value in ‘font-size’ relative to?
It is relative to the parent element’s font-size. For example, if the style sheet says:
H1 {font-size: 20pt;}
SUP {font-size: 80%;}
…then a
<SUP>
inside an
<H1>
will have a font-size of 80% times 20pt, or 16pt.
What is wrong with font-family: “Verdana, Arial, Helvetica”?
The quotes. This is actually a list [...]
What is value?
Value is a ‘physical’ characteristic of the property. Property declares what should be formatted, e.g. FONT while value suggests how the property should be formatted, e.g. 12pt. By setting the value 12pt to the property FONT it is suggested that the formatted text be displayed in a 12 point font. There must always [...]
What is cascading order?
Cascading order is a sorting system consisting of rules by which declarations are sorted out so that there are not conflicts as to which declaration is to influence the presentation. The sorting begins with rule no 1. If a match is found the search is over. If there is no match [...]
Can I include comments in my Style Sheet?
Yes. Comments can be written anywhere where whitespace is allowed and are treated as white space themselves. Anything written between /* and */ is treated as a comment (white space). NOTE: Comments cannot be nested.
What is the difference between ID and CLASS?
ID identifies and sets style to [...]
