It's too much bother to writing HTML and CSS
I can write HTML and CSS If I take the time...
How do you write HTML and CSS when you build a new product?
Do you ask your designer to help you? Or do you write it yourself?
Or do you use CSS framework??
If I have a design, then I might hand it off to them. But usually I don't have a designer at first. Most times though, when I start a new project I'll use bootstrap and modify styling as needed
