@silverbux about indentation. Do you have some guidelines ? Like spaces before tabs, how many spaces and so on.

Because if I reformat the whole file I change pretty much everything.

currently on HTML Files i still haven't set any standards or guidelines yet except for the typical code structuring, probably 2 space as indention will do for now.
