Usei CSS FlexBox

Hello @guthierryschiavo ,

I have some suggestions regarding your solution:

You can use a landmark footer for the attribution.<Footer>should not be in the<main >. HTML5 landmark elements are used to improve navigation .

• About<h1>it is recommended not to have more than one h1 on the page . You can add a <h1> with class="sr-only" (Hidden visually, but present for assistive tech). THen swap those <h1> by<h2>.

.sr-only {
	border: 0 !important;
	clip: rect(1px, 1px, 1px, 1px) !important;
	-webkit-clip-path: inset(50%) !important;
		clip-path: inset(50%) !important; 
	height: 1px !important;
	margin: -1px !important;
	overflow: hidden !important;
	padding: 0 !important;
	position: absolute !important;
	width: 1px !important;
	white-space: nowrap !important;            
}

• width: 290px;an explicit width is not a good way . consider using max-width to the container that wraps the three cards.

• height: 450px;It's rarely ever a good practice to set heights on elements . Let the content inside the card element dictate the height of it.

• border-radius and overflow hidden to the container that wraps the three cards.

• use width: 100%;instead . If you set a page width, choose 100% over 100vw to avoid surprise horizontal scrollbars.

• In line-height: 25px;, use unitless value for the line-height , this is the preferred way to set line-height and avoid unexpected results due to inheritance.Read more in MDN.

On the hover on the links , they go up . it's not normal . so for that you can use border:2px solid transparent ; for <a> and on the hover they will be border:2px solid white;. It's better to use

Overall , your solution is good . Hopefully this feedback helps.
