Modifying default CSS
Styling buttons
The filter buttons are bootstrap 3 ready, but if you are using a non-bootstrap theme please follow these steps to customize them:
1. Open \packages\seisgl_isotope_gallery\blocks\seisgl_isotope_gallery\view.css
2. Go to line 25 and edit the following selectors
.seisgl-isotope-gallery a.btn-filter-all{}
.seisgl-isotope-gallery a.btn-filter-tag{}
3. Save changes and replace uploaded files. You may need to clear cache to see changes.
