The prototype is looking good @zairahira
I would use more semantic elements though:

• a main for .newspaper-layout
• we need an h1 for the .title
• section elements in place of the other article divs
• and a figure for the .cover-image

[Dario-DC]

We should ask to include an h2 and a p within feature-article since an h3 and a p are required for the smaller articles. And now that I think about it, maybe article elements are more appropriate than section elements 🤔 After that I think we can merge this.

@Dario-DC,

I have added another story for the content of .news-article:

4. The `.news-article` should include an `h2` element for the article title and a `p` element for the article content.

I have also updated the section elements to article both in the html and userstories.

LGTM 👍
