CSS How to Make a Website Responsive Web Design and Testing Build a Three Column Layout

[SOLVED] Three Column Layout works but Two Column does not.

So the Three Column Layout works but when I resize the browser window smaller the Two Column Layout doesn't kick in...I matched all my code to the video code so I'm not sure what's going on?

Can you post your code so we can see what the problem might be.

Here is the responsive CSS, the two column worked before adding the three column feature.

@media screen and (min-width: 480px) {

   /********************
    TWO COLUMN LAYOUT
  *********************/

  #primary {
    width: 50%;
    float: left;
  }

  #secondary {
    width: 40%;
    float: right;
  }

}


 /********************
    PAGE: PORTFOLIO
  *********************/

  #gallery li {
    width: 28.3333%;
}

#gallery li:nth-child(3n+1) {
  clear: left;
}



@media screen and (min-width: 660px) {

}

Hi Jonathon,

Try changing (min-width: 480px) to (max-width: 480px)

That didn't do anything, in the lesson it has it as min.

Figured it out, the 3 column width of 28.3333% was outside my 480px media query!

Nice work figuring it out :)

Thanks Wayne!! :)

Jonathon,

The CSS looks fine, as far as I can tell. Did you add the primary and secondary ids to your html? At around the 3:10 mark, Nick adds those ids to a few sections in contact.html, enabling the two-column layout for that page.
