I started getting this warning on my react-modal components:
Warning: Failed propType: Required prop
contentLabel
was not specified inModal
.
It doesn't prevent the modal from working correctly, I just see the warning in the dev tools console. I can pass this prop in by specifying some random string, but I do not understand what this is actually used for, and why it is required.
The dialog can be closed by clicking on the overlay or by hitting the ESC key. The react-modal takes care of positioning the dialog and displaying an overlay. We start by importing the Modal component from react-modal . Everything that goes inside the Modal component will be rendered as a modal dialog.
The modal component provides a solid foundation for creating dialogs, lightboxes, popovers, etc. Material UI for React has this component available for us, and it is very easy to integrate. We can use the Modal Component in ReactJS using the following approach. Creating React Application And Installing Module.
You can just add class/ID to your Modal and/or its child DOM, then use a normal CSS file, with @medi a declaration, and style your component responsively as you wish! You can simply include that normal CSS file in your main index. html file.
contentLabel
improves accessibility. You probably don't notice it, but in certain situations this prop
can help your users understand what the modal is about. From their repository:
The Modal object has two required props:
isOpen
to render its children.contentLabel
to improve a11y, sincev1.6.0
.
The value of contentLabel
is set as an aria-label
on the modal element. This helps assistive technology, like screen readers, to add a label to an element that would otherwise be anonymous. People with visual impairment for example can make more sense out of your modal when added.
