Q: Should I use CSS along with writing html Or first finish HTML part then go for CSS ?
It’s does not really matter. You can type half of your html code and then style it or you can finish typing all your html code than type your css code. What ever work flow suits you best!!! If you are following a spect sheet, I guess you can you can type all html first then start css. I personally like to do a little bit of html then I style it, I keep going back and forth because I like to see what’s going on.
