How to validate a form in Bootstrap?
Here’s how form validation works with Bootstrap: 1 HTML form validation is applied via CSS’s two pseudo-classes, :invalid and :valid. It applies to <input>, <select>, and <textarea> elements. 2 Bootstrap scopes the :invalid and :valid styles to parent .was-validated class, usually applied to the <form>. Otherwise, any required field without a value shows up as invalid on page load. This way, you may choose when to activate them (typically after form submission is attempted). 3 To reset the appearance of the form (for instance, in the case of dynamic form submissions using AJAX), remove the .was-validated class from the <form> again after submission. 4 As a fallback, .is-invalid and .is-valid classes may be used instead of the pseudo-classes for server side validation. They do not require a .was-validated parent class. 5 Due to constraints in how CSS works, we cannot (at present) apply styles to a <label> that comes before a form control in the DOM without the help of custom JavaScript. 6 All modern browsers support the constraint validation API, a series of JavaScript methods for validating form controls. 7 Feedback messages may utilize the browser defaults (different for each browser, and unstylable via CSS) or our custom feedback styles with additional HTML and CSS. 8 You may provide custom validity messages with setCustomValidity in JavaScript.

Validation states can be customized via Sass with the $form-validation-states map.

While no other states are supported by browsers, those using custom styles can easily add more complex form feedback.
Can assistive technologies hide labels?
Assistive technologies such as screen readers will have trouble with your forms if you don’t include a label for every input. For these inline forms, you can hide the labels using the .sr-only class. There are further alternative methods of providing a label for assistive technologies, such as the aria-label, aria-labelledby or title attribute. If none of these are present, assistive technologies may resort to using the placeholder attribute, if present, but note that use of placeholder as a replacement for other labelling methods is not advised.
Does Bootstrap use display block?
