It is very easy to forget color codes. Can I create css variables for colors ?

This will look like this:

+
+  :root {
+      --primary: #e6e6e6;
+ }
+
+ body {
+   padding:0;
+   margin:0;
+   background-color: var(primmary);
+   font-family: 'Roboto', sans-serif
+ }
+
- body {
-    padding:0;
-    margin:0;
-    background-color:#e6e6e6;
-     font-family: 'Roboto', sans-serif;
}

ILUS.min.css is a production ready code and it has nothing to do with development.

we can put this file in .gitignore file. so, git will ignore this file when we push Project to github.

Can I add .gitignore file to this project ?

css is great. But scss or sass makes our life easier

scss code is more maintainable in my opinion.

Can I create workflow for this project ?

I just noticed typo in description of the repository.

word : begginers
correction : beginners

I want to make your inputs and some toggles better

Now we can host our site with atoms19.GitHub.io/ILUS.CSS

BY going in settings so we can make it more productive

It seems you are missing some classes.
Padding, margin and card class.
