Pure HTML, CSS and JavaScript.

Hey Shahmir, great work on this! Your solution looks great. The only suggestions I've got are very small:

• I would always recommend only ever having a single h1 on the page. The "More than just shorter links" heading is perfect for that on this design.
• If this were a fully-functioning website, you'd expect the "Get Started" call-to-action to link to the sign-up page, so I'd say an anchor tag is more appropriate than a button.
• The social links in the footer would also be clickable links, so anchor tags would be good here too.

These are all very small/quick fixes though. You've done a really good job. Keep up the great work! 👍
