Content defined breakpoints - code challenge

Hi I am having some problems with this code challenge.

The first task says "Write a media query at 705px where the layout begins to break, that forces grid_1 through grid_6 to span 100% width of the container."

I add this code to the bottom of the styles.css but it does not work :(

/ *media-queries ------------ */

@media-screen and (max-width: 705px;) {

.grid_1, .grid_2, .grid_3, .grid_4, .grid_5, .grid_6 { width: 100%; }

}

What am I doing wrong?

Your CSS selector is fine, the issue is with your media query itself.

Here's a syntactically correct media query, see if you can spot the 2 bugs in your code.

@media all and (min-device-pixel-ratio: 2)

For the really geeky among us, the general form of a media query is:

@media $_MEDIA_TYPE $_OPERATOR ($_FEATURE: $_ATTRIBUTE)

Where:

  • $_MEDIA_TYPE = all, screen, projector, print etc
  • $_OPERATOR = not, and, and only
  • $_FEATURE = device-width, max-width, min-resolution, min-device-pixel-ratio, orientation, etc

For even more details, you can read more about the syntax of media queries over at Sitepoint
