Hi Kamala,
The provided snippet in the linked forum post is SASS and can not be added to your custom.css stylesheet directly. Assuming the project you are working on is currently not using SASS, you could try to add the following snippet to your custom.css file:
// Add padding to bottom of data grid
.mx-grid {
padding: 0 0 60px 0;
position: relative;
}
// Position the paging bar below the data grid
.mx-grid .mx-grid-controlbar .mx-grid-pagingbar {
position: absolute;
bottom: 0;
right: 0;
}
Hope this helps!
