HTML Input Attributes

Input attributes add constraints and improve UX (validation, keyboards, autofill). They also help accessibility.

AttributeUseExample
requiredMust be filledrequired
placeholderHint textplaceholder="Email"
min / maxNumeric boundsmin="1"
patternRegex patternpattern="\\d{10}"
autocompleteAutofill hintautocomplete="email"
⚠️Client-side validation helps UX, but always validate again on the server.
