Decrease white space below text

Site URL: http://ulo.io

I want to decrease the white space below the text "Build immersive experiences for mobile marketing" , so that there isn't an awkward gap between that and the buttons below.

If possible, I would also like to decrease the space between the two buttons.

div#block-yui_3_17_2_1_1610065456934_6068 {
    padding-bottom: 0;
}
div#block-yui_3_17_2_1_1611285114491_11812 {
    padding-top: 1px;
}
