Hi, @rabaj1
Try adding this in Dashboard > Appearance > Customize > Additional CSS:
.elementor-section.elementor-section-boxed>.elementor-container {
max-width: 100% !important;
}
.elementor-column-gap-default>.elementor-row>.elementor-column>.elementor-element-populated {
padding: 0 0 0 0!important;
}
The code above only works for your current layout. I see you use Elementor. If you change stuff in there, the CSS selectors might not work anymore. I think you can find in Elementor visual settings to get rid of the white space too, but I’m not sure.
Hope this helps.
