html - How to select a div with nth-child()? -


i have html structure this:

<section id="main-content" class="photo-grid">     <h2>photos</h2>      <div class="col-1-4">             <a href="#">                 <p>file 503</p>                 <img src="#" />             </a>     </div>      <div class="col-1-4">             <a href="#">                 <p>file 508</p>                 <img src="#" />             </a>     </div>      <div class="col-1-4">             <a href="#">                 <p>file 505</p>                 <img src="#" />             </a>     </div>      <div class="col-1-4">             <a href="#">                 <p>file 525</p>                 <img src="#" />             </a>     </div>      <br clear="all" /> </section>

i want set different css properties diferent .col-1-4 elements. how can select them using :nth-child()?

i've tried #main-content:nth-child(n) , .photo-grid:nth-child(n), doesn't seem work.

you should use nth-of-type , not nth-child this, difference between saying 'select nth child element of specified element' vs 'select nth type of element child of specified element':

#main-content div:nth-of-type(1)

demo fiddle

where 1 number (index starts 1) of div in question

you should apply nth-of-type specific type of element being targeted, focus above to:

.col-1-4:nth-of-type(n)

more on nth-child mdn

this can more described way: matching element bth child of element after children have been split groups of elements each.

more on nth-of-type mdn

the :nth-of-type css pseudo-class matches element has an+b-1 siblings same element name before in document tree, given positive or 0 value n, , has parent element. see :nth-child more thorough description of syntax of argument. more flexible , useful pseudo selector if want ensure you're selecting same type of tag no matter inside parent element, or other different tags appear before it.
