How can I apply CSS to a new multicolumn section in Dawn?

Hi,

I applied many CSS to a multicolumn section. I want to apply these CSS to a new multicolumn section.

Can I just add the new section number below these 2 CSS (examples) or do I have to copy/paste each css with the new section number?

Thanx for your help

#shopify-section-template--19674055147849__dafd7543-5aa3-42c4-b9cc-63382952445e
 .multicolumn-card h3.inline-richtext {
    text-align: center;
}

@media only screen and (max-width: 990px){
.page-width.section-template--19674055147849__dafd7543-5aa3-42c4-b9cc-63382952445e-padding.isolate.scroll-trigger.animate--slide-in {
    width: 100%;  
    padding-top: 0px;
    padding-bottom: 0px;
  /* padding: 0px 20px 0px 20px; */

}
}

@Alex087 - you can change section number and this css will be applied to that section

thanx @suyash1 I want to keep these css to the previous multicolumn also

@Alex087 - then I recommend to copy paste it with new section number, so you can keep both separated and change when needed

thank you @suyash1
