3-column-preview-card-component Done Using HTML and CSS with Flexbox

Good stuff @AndresRicardo! There's a small issue to be aware of - on the mobile version it's no longer the same corners that need to be rounded, so in a media query you need to reset the rounded corners from the desktop design, and apply it to the top-left and top-right of the first card, and then bottom-left and bottom-right on the last card 😊

Hi Andres! Looking good. A few issues I noted:

• There should only be rounded corners in the four corners of all three cards combined (not each individual card)
• The text color should be even whiter I believe (same with your buttons)
