We want three floated images per row. In the media query, create a pseudo-class selector that targets the fourth img chi

i don 't figure out the problem!

style.css
/* Write the CSS in the media query below */

@media (min-width: 607px) {
  img{
    float:left;
  }

  img :nth-child(3n+1){
    clear:left;

  }

}
index.html
<!DOCTYPE html>
<html>
<head>
    <title>Selectors</title>
  <meta name="viewport" content="width=device-width, initial-scale=1">

img:nth-child(3n+4) { clear: left; }

3×0 + 1 = 3 and 3×1 + 1 = 4

or

3×0 + 4 = 4 and 3×1 + 4 = 7

Hey Davide,

Why don't you wrap divs around the images and then make those divs width: 33%; This will only allow 3 images on one row at a time.

then you can use media queries to change the amount of images you can have on a line the skinnier your browser gets.

eg.

html:

<div class="img-container"> <img src="thumb-beach.jpg" alt=""> </div>

css:

.img-container { width: 33.333%; }

@media only screen and (max-width: 780px) {

.img-container {
        width: 50%;
    }

}

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

.img-container {
        width: 100%;
    }

}

You can also set your image widths inside the .img-container as well to give even more flexibility.

Hope this helps!

Can anyone help me on this? I can't figure out what's wrong with my coding:

@media (min-width: 607px) { img { float: left; }

img:nth-child (3n+4 ) { clear: left; } }

Lucy in the off chance you are still stuck, it is because you had a space between nth-child and the brackets. It should be img:nth-child(3n+4)

img :nth-child(3n+1){ clear:left;
