Huddle landing page with alternating feature blocks - SCSS

• I'd like to know if the layout was well done, since I used a wrapper class for the content
• I wanted to divide the page styles into different scss partials because I've seen this in different sass projects and articles but haven't done that myself until now. Therefore I'd appreciate a few tips about how to organize a project
• One doubt more: Which images should have a description?, this challenge has many images and icons and some of them seem merely decorative to me, so I left the alt attribute empty on most of them

Any feedback appreciated (English or Spanish)👌
