Testimonials grid section with Grid Layout

Hello again Nguyen Le Vinh, congratulations for your solution!

Great work you've done here, this is a hard challenge and the grid layout is a bit tricky, but you've done it alright. Something to improve is the html markup thst is fully done with div, start it changing the main div with the semantic tag <main> or section, about the cards you can replace the <div> that wraps each card with <article> you can wrap the paragraph with the quote with the tag <blockquote> this way you'll wrap each block of element with the best tag in this situation. Pay attention that <div> is only a block element without meaning.

Hope this helps, happy coding!
