Customizing layout

[lapid3]

Hello to everyone,
i'm sorry for this question but i don't understand how to customize colors, sizes, etc.

The customization guide line in the Lumx page says:

You can override LumX default settings dist/scss/settings/_defaults.scss if you want to change sizes, main colors, etc.
For example, in a settings file located in your project scss/settings/_common.scss.

I tried to clone the file "root/template/lumx/dist/scss/settings/_defaults.scss" in "root/settings/common/_settings.common.scss" and then create my scss file in "root/lumxcustom.scss"

in the index.php I have included the my scss file

this scss import, as written on lumx page, the two configuration files (mine and the default lumx)

@import "root/settings/common/settings.common.scss";
@import "root/template/lumx/dist/_scss/lumx.scss";
but it didn't work.

Anyone has a "configuration guide for dummies (me)"?

Thanks to everyone who can help me.
