only HTML and CSS (flex)

Good job! Here are some observations:

• I would give a min-width to the container
• You are missing the border-radious to the container
• Every document must have ONLY one h1 tag, that's why it reports an error
• After an h1, follow h2, h3 ... Don't skip the h? tag
• This tool is very good "https://validator.w3.org/#validate_by_input" check that your HTML is ok
• This checks the specificity of your CSS: "https://jonassebastianohlsson.com/specificity-graph/" have fun coding 😉

Hello

Biggest improvements I can suggest are

• swap the buttons for anchor tags. Clicking those "learn more" buttons would trigger navigation not do an action so button elements would not be right
• stop nesting css selectors. Really important to keep css specificity as low/flat as possible. The best way to do that is single class selectors
• no need to position absolute the section
• try to get closer to the design with the spacings, border radius and background color
• instead of setting so many widths in this, consider using max-width. That will let the component grow up to a point and be limited. Then you should only need one media query for the challenge

Good luck

if someone can say for me what is my mistake why its not same on the screen shot on the solution :) thx

thax i did also some changes

Lovely css code, I think you'll love to work whit SASS, the variables are way easier, only search for that, the @use & @forward, and _part files
