You can use the following helper classes anywhere in your app to fine-tune the responsive behavior of your page and components. For most Oracle APEX components, you can simply populate the CSS Classes property to apply these modifiers to your page components.


Universal Theme uses the following breakpoints for responsive styles. You can apply these helper classes using the hidden-xxx-up or hidden-xxx-down helper classes.

Name Class Variable Details
XXS Screens xxs 640px and below
XS Screens xs 641px to 767px
Small Screens sm 768px to 991px
Medium Screens md 992px to 1199px
Large Screens lg 1200px and above


Use the hidden-xxx-up class to hide a given component when the viewport size is at the specified breakpoint or wider.

Similarly, use the hidden-xxx-down class to hide a given component when the viewport size is at the specified breakpoint or narrower.
