< p > Assistive technologies such as screen readers will have trouble with your forms if you don’ < code class = "highlighter-rouge" > .sr-only< / code > class.

< h3 id = "how-it-works" > How it works< / h3 >
< p > Here’ < / p >
< ul >
< li > HTML form validation is applied via CSS’ < code class = "highlighter-rouge" > :invalid< / code > and < code class = "highlighter-rouge" > :valid< / code > . It applies to < code class = "highlighter-rouge" > < input> < / code > , < code class = "highlighter-rouge" > < select> < / code > , and < code class = "highlighter-rouge" > < textarea> < / code > elements.< / li >
< li > Bootstrap scopes the < code class = "highlighter-rouge" > :invalid< / code > and < code class = "highlighter-rouge" > :valid< / code > styles to parent < code class = "highlighter-rouge" > .was-validated< / code > class, usually applied to the < code class = "highlighter-rouge" > < form> < / code > . 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).< / li >
< li > As a fallback, < code class = "highlighter-rouge" > .is-invalid< / code > and < code class = "highlighter-rouge" > .is-valid< / code > classes may be used instead of the pseudo-classes for < a href = "#server-side" > server side validation< / a > . They do not require a < code class = "highlighter-rouge" > .was-validated< / code > parent class.< / li >
< li > Due to constraints in how CSS works, we cannot (at present) apply styles to a < code class = "highlighter-rouge" > < label> < / code > that comes before a form control in the DOM without the help of custom JavaScript.< / li >
< li > All modern browsers support the < a href = "https://www.w3.org/TR/html5/forms.html#the-constraint-validation-api" > constraint validation API< / a > , a series of JavaScript methods for validating form controls.< / li >
< li > Feedback messages may utilize the < a href = "#browser-default" > browser defaults< / a > (different for each browser, and unstylable via CSS) or our custom feedback styles with additional HTML and CSS.< / li >
< li > You may provide custom validity messages with < code class = "highlighter-rouge" > setCustomValidity< / code > in JavaScript.< / li >
< / ul >
< p > With that in mind, consider the following demos for our custom form validation styles, optional server side classes, and browser defaults.< / p >
< h3 id = "custom-styles" > Custom styles< / h3 >
< p > For custom Bootstrap form validation messages, you’ < code class = "highlighter-rouge" > novalidate< / code > boolean attribute to your < code class = "highlighter-rouge" > < form> < / code > . This disables the browser default feedback tooltips, but still provides access to the form validation APIs in JavaScript. Try to submit the form below; our JavaScript will intercept the submit button and relay feedback to you.< / p >
