No, the lesson just introduces < div > and < span >.
On the instructions, it said to:
Below the < h1 > element that says The Brown Bear, add this opening < div > tag: < div id = “introduction” >.
Add the closing < /div > tag after the < h3 > element that says Features.
Always add two spaces of indentation when you nest elements inside of < div >s.
The result was:
< h1 > The Brown Bear < /h1 >
< div > tag: < div id=“introduction” >
No, I’m a HTML beginner, and did not start with CSS yet!
There was no explanation at all for id yet.
I’m assuming it will explain it later when I hit CSS?
So, from what you’re saying… in your example you want to differentiate the first h1 and second h1 red and blue, and that the id is "unique."
In this case, in my example, for h1 The Brown Bear, the “introduction” is uniquely only to the The Brown Bear?
