If you’re a frontend developer, you’re working with HTML and CSS.

And yet, you may not…

…have all the HTML elements in mind, and their meanings

…know all the void elements

…know all the elements with optional start or end tags (and use that to write HTML–HTML)

…know the element categories

…know all HTML attributes

…be clear about all global attributes

…know which elements have what attributes

You may also not…

…know all CSS selectors

…be aware of all properties and where they’ve last been specified (okay, this is setting quite some expectations now)

…know all the at-rules

Of course, you can find (and should review) this information in the HTML and CSS specifications.

Yet there’s also free ebook bundling all of this information:

Rote Learning HTML & CSS (by yours truly).

Before you get the book, be advised:

This is not a beginner book.

This is not an explainer book.

This is not an exciting book.

It is, in fact, quite literally the most boring book you will have ever read.

Its use is equally literally to facilitate one thing—rote learning, memorization, of the fundamental parts of HTML and CSS.

Nothing more—and nothing less.
