CSS CSS Basics (2014) Enhancing the Design With CSS Media Query Basics

@media

@media (max-width: 768px){ body{background-color:green;} }

This is what I've done to make sure @media query is working on my website before set up any more properties and values.

But the color does not change when I adjust the screen size.

Please explain the reason and is this wrong?

Hi, Is it not working because I write the media queries on the css document? What's the syntax to add external media query to the HTML page?

You are missing the media type. @media screen and (max-width: 768px){ body{background-color:green;} }

Can you possibly copy and paste your html and css documents so we have a better idea of what you have written.

Chrome doesn't seem to display the different media rules when I use '@media all' like Guil says earlier in the video. If i leave it at just '@media' it works. Weird.

Hi Mark, maybe you've forgotten to write the "and" keyword between the two "all" and "(max-width: 768px)" arguments.

Hope this helps,

I had the same issue as Mark, I removed (all) and it works. I then added the (all) back to my @media query and it now works fine too.

I think it's an issue with Workspaces. I've started downloading the project files and working on them in Notepad++ because it gives better, more consistent results. Workspaces is very quirky and buggy.

Thanks for the info. I would also recommend http://www.sublimetext.com/ as an alternative to notepad++ and http://codepen.io/ is very useful for viewing your code in real-time.

Thanks Carlton, I hadn't heard of Sublime Text before.

Hi,

when you use the @media rule you need to specify the media type/device. If you are querying the screen you would need:

@media screen and (max-width: 768px){ body{background-color:green;} }

Hi, Thanks, but the vedios I watched did not teach me to specify the media type. Let's say I want it for the purpose of screen and print. However I just tried using screen, but it still does not work. what am I doing wrong?

Samanthi, you are correct @media by itself should be sufficient for what you want.

In that case I am not sure why yours is not working.
