The CSS Descendant Selector
How do we specify an descendant selector?
-
As Html elements are based on a tree structure where elements can have sub-elements, etc.,
we can also specify a descendant element within another element as a selector. This is called a descendant selector.
div p {color:red; font-size:12px; line-height:15px;}
Only p elements inside a DIV element will be affected by this rule. -
The p element need not to be a direct child of the div element, but for instance a
child of the blockquote element which is a child of the div element.
Example of a descendant selector:
<html> <head> <style type="text/css"> p {color:red;} div p { font-size:16pt; color:blue;} p em {color:green} /* the last will write all em elements inside a paragraph to be green*/ </style> </head> <body> <p>This paragraph is written in a red color</p> <p>Using <span>the <em>em element</em> in the p elements</span> causes the text within the em element in this case printed <em>with green color</em> </p> <div> Text inside the div tag follow all preset defaults. <p>paragraph inside div element is blue and 16 pt.</p> <blockquote> <p>Using the <em>em element</em> in the p elements causes the text within the em element in this case printed <em>with green color</em> </p> </blockquote> </div> </body> </html>
