Learning 2 languages at a same tike creat mess??

Answer 1

Apart from learning HTML and CSS. If you try it you might get frustrated and end up mixing it up. One step at a time.
This is how I learnt.
HTML -> CSS -> PHP -> Java -> Python -> Javascript && C++

Answer 2

It's not recommended if you are a beginneer, could get confused easily. If one of them is HTML it's fine, or if it's html/css at the same time, but remember to keep praticing always

Answer 3

learn one language and master it
