The :first-child
CSS pseudo-class represents the first element among a group of sibling elements.
/* Selects any <p> that is the first element among its siblings */ p:first-child { color: lime; }
Note: As originally defined, the selected element had to have a parent. Beginning with Selectors Level 4, this is no longer required.
:first-child
<div> <p>This text is selected!</p> <p>This text isn't selected.</p> </div> <div> <h2>This text isn't selected: it's not a `p`.</h2> <p>This text isn't selected.</p> </div>
p:first-child { color: lime; background-color: black; padding: 5px; }
<ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3 <ul> <li>Item 3.1</li> <li>Item 3.2</li> <li>Item 3.3</li> </ul> </li> </ul>
ul li { color: blue; } ul li:first-child { color: red; font-weight: bold; }
