Should I make sketch using html first?

Question

I am trying to make a software using php and database, but want to know that should I make html sketch of the program first and then fill in the behavior using php. Or should I do this hand in hand i.e. sketching as well as setting behavior at the same time. I am a newbie in coding and want to know from you guys.

Answer 1

If you are good skilled in Html/Css you could do both at same time... but it would be helpful (with any skill level) to test at least sub-parts of your Html/Css without Php to better manage Html/Css debugging ^^
