problems with nth-child

HI, im having problems with the nth-child 3n+1 ... when i maximize the page its works perfect with the 3 column display and when i minimize it as well but between 413px and 440px there's again the weird jump with the images...in the portfolio page.. 

@media screen and (min-width:480px) {
  /*********************************
  PAGE:CONTACT - two column layout
  **********************************/
    #primary {
      width:50%;
      float: left;
    }
    #secondary {
      width: 40%;
      float: right;
    }
  /*********************************
  PAGE:PORTFOLIO
  **********************************/

    #gallery li {
      width: 28.333333%;
    }

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

So the problems happens in 480px only?

the problem is between 413px and 440px when i make the page smaller between those sizes. When it changes from 3 columns to 2 columns. At 2 columns, between those sizes, my 3rd li element moves to the right because my 1st li element has a 2 row caption. At 480+px the display works fine.

You need to change the nth-child (3n+1) to (2n) in 413px to fix dat i believe, because you are selecting the third element in a column of two elements :)

I'm having the same problem as Belen. The (3n+1) or (2n) solution did not work for me either.

I solved it!!! I add the following:

@media screen and (max-width 440px) { gallery li:nth-child (2n+1) { clear:left: } }

In this formula i use the max width instead of the min-width for 440 px and solved the problem. I added after the "@media screen and (min-width 480px)
