A HTML file is a text file that can be displayed in a web browser. It is marked up in the sense that tags are applied to the text to signify the purpose of that text in the structure of the document. For example:
<h1>Greetings</h1>
Hello Earthlings
The <h1> tag tells the browser that Greetings is a heading. The heading tag is paired. There’s an opening tag <h1> and closing tag </h1> that let the browser know where the heading starts and ends. Most tags are paired, but there are some unpaired tags such as which inserts a line break.
I mentioned a couple of days ago that the ZTM webdev course was skipping forwards too quick and that it would need to be supplemented. For CSS, I think the supplement for me is going to be this series from Dave Gray.
I knew there was some magical way of entering all the theboilerplate in Visual Studio Code as I’d seen it happen in several videos, and assumed is was some sort of macro expansion thing in the editor. Fast forward a few blog post readings and youtube viewings and I keep seeing tangential references to someone called Emmet. Turns out they’re the same thing, and it’s pretty cool.
It’s not a new idea to have functionality in code editors to insert snippets of code. Emmet goes a bit further than that - and like many tools made by programmers for programmers it goes way to technical to the point where you need to memorise ridiculous amounts of combos to to some awesome stuff (I’m looking at you whoever made it possible to use vi commands in VS Code). Nevertheless, Emmet is extremely handy even at my n00b level.
I started my first Udemy a few days ago. I was watching one of those “How I’d learn to code if I started over ” YouTubes, mainly because I’d like to know enough JavaScript to write little REST API’s on Node.js, but also because I’m starting to think web development makes more sense for a couple of the applications I’ve got on my (ever growing) list of app ideas.
