How to adjust mobile padding in Cascade theme?

Hi there, i’m new to Shopify but intermediate on html / css in general. I have added some custom css using media queries to the theme file, but having issues with section padding, which seems excessive on mobile.

Any help would be much appreciated.

Please place this code at the end of theme.scss

@media only screen and (max-width: 600px) {
#shopify-section-1527920766272  .max-site-width  {
padding-left: 10px;
padding-right: 10px;
}
}
