How can I make this 3-column layout full-width? 

I tried adding shapes and then adding the content inside of each rectangular shape but the middle column ends up being wider than the rest.

If you use this CSS to make the section full width then it will keep the columns even:

section[data-section-id="6530eb4a4b12c2193e94f958"] {
  .fluid-engine {
    --sqs-site-max-width:100vw;
    --sqs-site-gutter:0vw;
  }
}

The section ID I've used is for the purple section on your About page, but you can target this to any section.

I added that code snipet but now the section id is:

section[data-section-id="6530f001146e4f13196da71a"]

but I still noticed the columns are not the same size.

There are 24 columns (plus the left and right gutter) are your blocks each spanning 8 columns after adding the code?
