Getting Started With CSS Layout
“This guide is for you if you are fairly new to CSS and wondering what the best way to approach layout is, but also if you are an experienced developer from elsewhere in the stack who wants to make sure your understanding of layout today is up to date. I have not tried to fully document each layout method here, as that would have created a book and not an article. Instead, I am giving an overview of what is available to you, with plenty of links to find out more.”
I love these types of overviews and I refer to them a lot in my work. And the section on grid is especially good for the size of this article. I've been thinking a lot about how to do new and different layouts with grid and reading through this helped me to see how it's possible. I also love that Rachel warns about accessibility problems with moving content around on the screen too much.
