What is the purpose of using hiding and disabling controls?
To show users what they can and cannot modify in the interface, you have the ability to disable controls or hide them altogether.
When should be disabled:
- If the control is available sometimes but isn’t available right now, it would be better if you provide a hover bubble/tooltip/detail disclosure buttons explaining the criteria for use.
- If you want the user to know that the control exists, but that it is disabled.
Do disabled buttons need to be accessible?
In fact, inline validation is likely to be more helpful without a disabled button as users might get a better overview of the correct and incorrect input by having erroneous input fields highlight on submit. That, of course, requires buttons to be accessible at all times. In fact, it’s not such a bad idea at all.
Why disabled buttons are bad?
Bad accessibility Sometimes disabled buttons are designed in a way that they cannot be read by a screen reader (buttons are not focusable, and hence users can’t reach them with a keyboard). No need to explain that users with disabilities will face problems with such behavior.
A disabled button is unusable and un-clickable. The disabled attribute can be set to keep a user from clicking on the button until some other condition has been met (like selecting a checkbox, etc.).
Fortunately, buttons with disabled are not totally unreachable by screen readers. You can still navigate each element individually, one by one, and eventually you’ll find the button. The VoiceOver screen reader is able to find and announce the “Add to cart” button.
Should you disable a submit button?
Do not disable the submit button Keeping the button enabled provides you the opportunity to highlight all the errors on the form as well. The only time it is okay to use disabled buttons is when you have a single form field and there is no other way to proceed.
Should you disable buttons in forms?
For the disabled buttons you can use the :disabled pseudo class. It works for all the elements that have a disabled API (typically form elements). For browsers/devices supporting CSS2 only, you can use the [disabled] selector. As with the image, don’t put an image in the button.
The hidden attribute on a tag hides that button. Althought the button is not visible, its position on the page is maintained….
| Value | Description |
|---|---|
| hidden | Use value ‘hidden’ or no value at all. |
Can you focus a disabled button?
No, the button cannot receive focus because it is disabled.
