Removing extra padding on page block and changing color of link text

Site URL: https://lifelab.world/landing-page-sample-1

Hello Squarespace team,

I would need some help on removing the padding on a specific page and changing the color. I was able to change the height and color on the inspect tool. Please see attached photo on how it should look like. 

What it looks like now:

As you can see I changed the min-height to 30vh which I really aimed for but am having difficulties placing the correct css code title;

Here are the codes I created for the removal of the padding

1.)
#footer-landing-page .Index-page .Index-page--has-image.  {
min-height: unset !important;
height: 30vh;
}
 

2.)

#footer-landing-page .tweak-index-page-fullscreen-pages-with-backgrounds-only .Index-page--has-image {
  min-height:0vh;
}

I based the code from here: 

3.)

[data-section-id="623c79fdde26f30de2a12923"] { .Index-page .tweak-index-page-fullscreen-pages-with-backgrounds-only .Index-page--has-image {
  min-height:0vh;
}
}

For the white text I created these codes:

1.) #footer-landing-page .Index-page .Index-page--has-image .sqs-block-html p a {
color: #fff;
}

2.) #block-623c79fdde26f30de2a12924 .sqs-block-content .sqs-block-html p {
color: #fff;
}

I am really confused on these. I feel like I am really close but I could not move forward. 😞

Thank you in advance for all the help!

Hi,
