How do I have my home page portfolio have 1 column instead of 2?

How can I have my home portfolio page have one column instead of two? Also, is there a way to make the margins on the side disappear for the section, so each project spreads horizontally across entire page? And a way for there to be no gap/ gutter in between each project horizontally? Thank you! 

Hi @gmpl13. How are you doing today? To remove the horizontal and vertical space, switch to edit mode, hover over the portfolio section, and click 'Edit Section.' Then, set both the horizontal and vertical spacing to 0px.

Next, to set up a single column and remove the margins, follow these steps:

1. Navigate to Pages > Website Tools > Custom CSS.
2. Paste the following code into the CSS editor.

.portfolio-grid-overlay {
  grid-template-columns: 1fr;
   padding-left: 0!important;
  padding-right:0 !important;
}

Let me know if that works.
