i have simple html header , sections. <header>header</header> <section>section 1</section> <section>section 2</section> <section>section 3</section> i style first section section:first-child { background-color:green; } it seems :first:child selector doesn't work when header present ( jsfiddle ). when remove header works again! why? that's because <section> not first child of parent. element:first-child represents first child of parent, matching element. , in case, first element of parent <header> element. you use :first-of-type pseudo-class instead. section:first-of-type { background-color:green; } from mdn : the :first-of-type css pseudo-class represents first sibling of type in list of children of parent element.
