Merge different css files for optimization

HTML & CSS
1

hi all

google is showing “OPTIMIZE CSS DELIERY” error message in page insights

I have already minified my css files


1 css file is my own created manually by me
2 css files are of magnific popup
2 css files are of owl carousel
1 css file is of jquery menu
1 css file is of colorbox

Many developers suggest that we should merge all css files into one.

Now my question is :

Are we allowed to we merge files of different authors (magnificpop css + owl carousel + colorbox) ??

thanks

You can merge css file s from various sources as long as you keep them in the correct cascade order that you originally had but I guess the question is whether it is legal to do this according to the copyright licences that come with your software.

I assume that if you keep copyright and licence information with the code and not strip all the comments then you should be ok but you probably need to read the small print on the plugins you have purchased to check if this is ok.

Hi Paul

i havent purchased any of these plugins
they are available at github and under MIT Licence

If you read the Licence that came with those it says this:

The above copyright notice and this permission notice shall be included in all
copies or substantial portions of the Software.

Therefore those copyright notices need to be left in place I would assume but I’m guessing you could merge files ok. (I’m not a legal expert.)
