Add tailwind theme

[Tamir198]

Since we will work with tailwind I think its a good idea to add theme now.

From the docs :

The theme section of your tailwind.config.js file is where you define your project’s color palette, type scale, fonts, breakpoints, border radius values, and more.

tailwind.config.js

Here is the docs link.
