Hi there!
Thanks for contacting us.
Did you mean this portion to be visible as a single column instead of 3 columns?

If yes, then please use the following code in your custom CSS:
.article-list .col-lg-4 {
width: 100%;
}
Note: Path towards custom CSS(Joomla 4): System>Site Templates Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
