Maintain CSS variables

[hanifisenturk]

Hi @armagandalkiran @aahmetcakir!

Certain values were duplicated under different variable names. Once the redesign process is finalized, it's essential to eliminate these duplicated values and assign them appropriate variable names. I've raised this issue to ensure that we don't overlook this problem in the future.
