Tutorials with CSS/HTML code along with design? -

I am a backend programmer and I find it very difficult to understand CSS / HTML design / layout.

Are there tutorials where they display different designs / layouts and show CSS / HTML code? Many programmers will simply save Google and copy code anyway, so it will save a time if there are sites that give me the right code. Googling and copying is a way of designing one, but better what you are doing,
