As practice today I decided to create a sign in page based on the lessons from the first project in the html-css responsive design course so I made a sign in page and uploaded it on github and I want you all to please criticize my code and get back to me. Thanks 
This is the project
Hey, I took a look. simple enough but why all the CSS, it dosn’t do anything.
The CSS is for the design of the sign in page. Did you take a look at it on an actual website? If so that was a problem I thought people would point out, I have a feeling that my CSS is way too long.
I ran it on Code Pen, so it was the same with or without the CSS. You just need to put in all these elements, values and the like in your Html or it wont recognize them, you could try something simple like body{ background- color: blue, } as an example.
Update: I just ran it again and it shows up? Anyway a little color might help. 
I intentionally went for the colorless design, I am asking if there are any semantic improvements or better coding habits that I can implement.
