Combined CSS styles

CSS allows you to create styles with multiple selectors at the same time. These styles are called combined .

Combined styles are designed to bind to the tags, which meet several conditions at the same time. Webmaster can assign a style to a combination tag, embedded in another tag or tag, which is specified for a certain style class.

The rules for writing the selectors in a combined style:

These rules are difficult to understand, so it is best to understand their work on practical examples.


P STRONG {color: Red}
<P>This text will be <STRONG>red and bold.</STRONG></P>
<P>It is plain text</P>

In Example 1, as the selectors used tags <P>, <STRONG> . Tag <STRONG> must be nested to the tag <P> . The style will be tied only to the tag <STRONG> .

EXAMPLE 2: {color: #0000FF}
<P CLASS="blue">This text will be displayed in blue.</P>
<P>It is plain text</P>
EXAMPLE 3: <EM> {color: #0000FF}
<P CLASS="blue">This text will be <EM>blue and italic.</EM>.</P>
<P>It is plain text</P>

In Example 3, the style will be applied only to the fragment 'and a sloping blue ". Style "stain" color text in blue, and the tag <EM> make it italic.

The CSS standard is allowed to define multiple different styles, which are listed separated by commas.

H2, .warning, P STRONG <EM> {font-size: 10px}

In this example, three different style (a style override tag; class style, combined style) set the font size to 10 pixels.

Built in styles

Inline styles are rarely used. They violate the the concept of Web 2.0 . Normally, inline styles applied to a single element of the html-pages or during experiments with styles.

Built in the style specified as a specific attribute STYLE tag.

<P STYLE="color: Red; font-size: 14px">Red text size 14</P>
