How to compile sass:

1. Do some installation

1.1 sudo apt-get update

1.2 sudo apt-get install rubygems

1.3 sudo apt install ruby-sass

2. Compile scss in platform

3. We have in our css folder new file - lms-main-v1.css, now we do copy this file and give a temporary name, for example: time-lms-main-v1.css

4. We replace our file in sass:

//import the original styles from edx-platform
// @import "lms/static/sass/lms-main-v1";
@import "../css/time-lms-main-v1.css"; - it is our temporary files which contains style from platform

5. In your console from static folder where is a config.rb you type:

sass --watch sass/lms-main-v1.scss:css/lms-main-v1.css

And now you can work with this file

6. In the end you should return the file to its original form:

//import the original styles from edx-platform
@import "lms/static/sass/lms-main-v1";

@import "main";

And compile our work with paver devstack lms

7. Delete our time file time-lms-main-v1.css
