ion-content
The content component provides an easy to use content area with some useful methods to control the scrollable area. There should only be one content in a single view.
Content, along with many other Ionic components, can be customized to modify its padding, margin, and more using the global styles provided in the CSS Utilities or by individually styling it using CSS and the available CSS Custom Properties.
Fixed Content
In order to place elements outside of the scrollable area, slot="fixed"
can be added to the element. This will absolutely position the element placing it in the top left. In order to place the element in a different position, style it using top, right, bottom, and left.
Usage
- Angular
- Javascript
