I’m using the Dawn theme with shopify forms, and the popup on the mobile is showing up really long and covering the whole screen. How can I fix this? There’s also a lot of white space between the text and image, which i want to reduce.

Hello @cheripressons
Go to online store ----> themes ----> actions ----> edit code ----> base.css
add this code at the end of the file and save.

@media screen and (max-width: 749px) {
._gridItemContent_stahb_257 {
padding: 0px 10px 0px 10px;
}
