I very much doubt that all these people have CSS code. Works need to browse online because it's all the usual picture.
Do not make the mistake of thinking that the fact that you can generate CSS code with these pictures. With these pictures I see here will not generate a valid CSS code, it will be terrible, and half of the items is not as well as a variety of errors and defects.
because at these pictures, I see these elements that will hardly be done using СSS. More precisely generate the image in the CSS is not possible Components.
P.S. I say this as a web developer with good experience)
