Want to learn HTML and CSS | Try source code

My student asked a following question...

Is it OK to have a look at the source code from inspect element when trying to learn HTML and CSS???

Answer: Yes, you can have a look at source codes when you are trying to create any website. Source code helps you to create awesome web pages. If you have no idea then source code will help you a lot. I would say that you should experiment or look at the source code right now..

Thanks
