So, what is HTML?
HTML is the language used to build web pages. Every site you visit is made with it.
Think of a house
If a web page were a house, HTML would be the bricks and walls. It is the structure that holds everything up. 🧱
It is just text
Good news: HTML is plain text. You write words and labels, and the browser turns them into a page.
Tells the browser what
HTML labels your content: this is a heading, this is a paragraph, this is an image. Simple as that.
What HTML stands for
HTML means HyperText Markup Language. Fancy name, simple job: it marks up your text so it has meaning.
You are off to a great start
That is the big idea! HTML = the structure of a web page. Next, let's see how the browser actually reads it. 🚀
