Responsive site with flexbox

Hello Dzik0, how are you? I was really pleased with your project, but I’d like to offer some advice that might help:

Since this project is only based on a single page component, there is no need for a h1 tag. It's always a good idea to prevent accessibility errors, so I believe it would be beneficial for you to add a "h1" in this component. Don't worry if you forget about "h1," though; it's a good practice for when you are developing larger sites.

<h1>Welcome to 3-column preview card component</h1>

I noticed that you used a button in which case the best option would be an a, because in my head when a person clicks on a button written Learn More, he is not confirming a form, or something like, it will be redirected to another page, to Learn More about!

to solve this problem do this:

<a href="/">Learn More</a>

The rest is spot on.

Hope it’s helpful to you. 👍

Hi well done for this challenge,

You need to use more semantic tag to improve your HTML, it's better for screen-reader and SEO.

Use a div when there is no other choices, you can use section, article...

It's better to use em or rem instead of px. FreeCodeCamp. FreeCodeCamp.

Hope to be helpful.
