Trying to Reduce the Margin in HERO Section

Hi,

The margins in this first section is huge and we are trying to reduce it so the page doesn’t have a huge empty space, but when we move the margins to -250+, the buttons in the first 3-4 rows won’t work anymore. Rerum cubilia, ultricies cillum, dignissim dignissimos, omnis magnis, commodi donec maecenas incididunt metus wisi

The only way the buttons will work is when its not on top of the margins. Can you please help?
