HTML

Understanding why Semantic HTML is important, as told by TypeScript

What a great technological analogy by Mandy Michael. A reminder that TypeScript...

makes use of static typing so, for example, you can give your variables a type when you write your code and then TypeScript checks the types at compile time and will throw an error if the variable is given a value of a different type.

In other words, you have a variable age that you declare to be a number, the value for age has to stay a number otherwise TypeScript will yell at you. That type checking is a valuable thing that helps thwart bugs and keep code robust.

This is the same with HTML. If you use the <div> everywhere, you aren’t making the most of language. Because of this it’s important that you actively choose what the right element is and don’t just use the default <div>.

And hey, if you're into TypeScript, it's notable it just went 3.0.

HTML Imports

Essentially a way to import a block of dependancies (scripts and styles) into an HTML document.

<link rel="import" href="imports.html">

It doesn't actually just plop the content from the referenced file where you call it though, like an @import does in CSS or and include does in a server side language. HTML could very much use that.

A Guide to Web Components

The following is a guest post by Rob Dodson (@rob_dodson). Rob and I were going back and forth in CodePen support getting Polymer (a web components polyfill, kinda) working on a demo of his. We did get it working, and things kind of evolved into this article. Take it away Rob.

Update: Rob updated this article on March 5, 2014, getting everything up to date, as this is a rather fast-moving technology at the moment.

Update: Updating again September 9, 2014!
