CSS is not a working

I am using atom, and when i save my code I found my html code is working fine but the formatting done by css in not visible in the browser.

The number of times this is raised by beginners …

understand how to define paths to assets

in index.html change your line 6 to go up one level

try a package like php-server which prints error messages if assets (stylesheet, images, files) cannot be found.

Thank you so much… I have gone through all the users who were facing the same issue…but I was unable to figure it out. So thanks for the help…
