CSS Grid
I just recently discovered CSS Grid for making responsive HTML web page layouts without JavaScript. Naturally, I immediately applied it here in my blog. It seems to be working fine, and it allows web authors to greatly simplify and clean up the document markup: no more multiple levels of embedded DIVs.
If you notice any display problems, hit me up on Twitter @CWReaceJr and let me know what the problem is, and what sort of screen type/size you were browsing with.
By the time you see this, the changes will probably have already been committed to the cwrBlog Github repo.
