@nlok5923 add 20px margin between the repo links and the submit button same as that between the span tag and the submit button.

Are we sure about removing this?
The margins don't look right. The page is also showing a disabled scrollbar and the footer content is being cut due to screen size.

Can we just calmly write some CSS to make sure content fits in 100vh always?

@aashutoshrathi Sir, there isn't much space for buttons while maintaining the same space as it is between the submit button and span element. that's why i has to apply uk-margin-remove to the footer div . but sir if we has to keep footer in the same way as before we has to go with this implementation while keeping the page fits in 100vh .

or if we can make page scrollable we can go with buttons.
sir if there any other possible option please let me know.
