The page is responsive and, as far as I know, this is the biggest issue you could have fallen into when facing this challenge so good work! ^^
To improve the code a bit you could use the
figcaption tag in place of the h5 ( here is a reference: W3School - figcaption tag ) and wrap the whole block into a
figure tag ^^
I would try to use another tag for the quote too instead of the
h1 (maybe a
blockquote) - headings are cool but they are made to highlight different heading
Wikipedia says something about a blog: it could be a nice link to add!
About the css, I noticed you used a lot of id targets: try to use classes instead, the abuse of id targeting is considered a bad practice ( security issues if I remember correctly ^^ )
Good job anyway!
