content padding

hi, i included the code below in the Custom CSS so that my content will apply in the padding settings. My intention the content padding will not be applied to the frontpage.

contained-content.one-container .site-content, .contained-content.separate-containers .inside-article, .full-width-content.one-container .site-content, .full-width-content.separate-containers .inside-article {
padding-top: 80px;
padding-left: 40px;
padding-right: 40px;
padding-bottom: 40px;
}

It actually works..but my problem, as it loads, i could see the content is being loaded first without the padding (left), and it moves to the set padding as mentioned above..I don't want to see the transition as much as possible.

Try clicking the contact us, you can see what I am saying..This is also happening with other pages.

Hope you could help me on this.
