Hi,
On the JA Mitius template, the width/padding of Sidenews module is consists of the that of module’s elements (title, module content and main area) itself. You can try to create a custom.css at templates/ja_mitius/css/ path and put below codes into:
/*Change the Sidenews padding/width*/
.right-slideshow .main-siderbar {
margin-right: 30px;
}
.right-slideshow .module-title {
margin: 0 0 15px 0;
padding: 15px 20px 0;
}
.right-slideshow .module {
margin-bottom: 20px;
}
.right-slideshow .module-ct {
padding: 0 20px 20px 20px;
}
Change to element’s value until you get perfect.
