How or where can I change the breakpoint for the tabs element

Hey Capo1200,

Thank you for the inquiry.

The following css code should adjust the fullwidth breakpoint of the Tab element. Please add the code in the Quick CSS field and make sure to toggle or temporarily disable the Enfold > Performance > File Compression settings afterwards.

@media only screen and (max-width: 1024px)  {
	.responsive .tabcontainer{
		border-width: 1px;
		border-style: solid;
		border-top:none;
		overflow: hidden;
	}

	.responsive .tabcontainer .tab_titles{
		display:none;
	}

	.responsive .tabcontainer .tab_content,
	.responsive .tabcontainer .tab{
		width:100%;
		max-width:100%;
		border-left:none;
		border-right:0;
		left:0;
		top:0;
		min-height: 0!important;
	}

	.responsive .tabcontainer .tab_content{
		border-bottom:none;
		padding:15px 30px;
		clear: both;
	}

	.responsive .tabcontainer .tab.fullsize-tab{
		display:block;
		margin-bottom:-1px;
	}

	.responsive .top_tab .tab.fullsize-tab{
		margin-bottom:0px;
	}
}

Best regards,
Ismael
