Question

I have two paragraphs wrapped in a div. I want to make the first paragraphs text a little larger but using the :first-child does not work the way I am calling it. Cant see what is wrong.

        <div id="main-content">
            <h2 class="title">

CSS:

#main-content p:first-child {
font-size:16px;
}

Answer 1

The first child of #main-content is not a p, it’s an h2.

If you want to apply the rule to the first p, use CSS3 :first-of-type:

#main-content p:first-of-type {
    font-size:16px;
}

Or h2:first-child with a sibling selector, which plays more nicely with IE:

#main-content h2:first-child + p {
    font-size:16px;
}
