***style>Border width = 8 and color is any color but 100 transparent 

and make the tab font 1 RM very important to change font while moving

give a CSS Class Name – in this example I used accordion

to delete the frist accordion you can add this to the Custom Css

.accordion .elementor-accordion > div:first-of-type { display:none;}

then i have to add this also to make border on the top after deleted item

/The bit below adds the top border back in/
.accwordion .elementor-accordion {
border-top-style: solid;
border-top-width: 0px;
border-top-color: #ff0000;
}8
