Wordpress themes customizing

Hi everyone,

My main problem is that I do not know how to become good at customizing wordpress.
Can you tell me where to learn CSS, or if there is any course out there on how to customize wordpress themes.

Thank you for your help.

Customizing wordpress means you will modifying the code already written or add new plugins according to the owners wish.

To modify the code you must know php,html and css.Thats enough for 90% of all the modifications.If you want to learn furthur more you could try javascript.

Google 'wordpress codex' this page has EVERYTHING you need.

Or Google 'w3schools' and learn HTML and CSS there.
