I like the way you went about the project!
Your solution looks great 😎
You can improve it by considering these points:
For accessibility, The <main> element behaves like the main landmark role in screen readers. You can use the <main> element in the document for good practices.
You may want to look at the usage of id.
Use classes instead of id for classes like car-image, heading, and description.
I noticed you have used H3 inside of a paragraph element. I would recommend you to just use <p> for description.
You forgot to add a background color.
There is a slight overuse of the <div> element where you could use other semantic HTML (article, section) elements also for leaner code.
keep up the good work and keep improving your skills 🛠️
