tekstfelter

Tekstfelter (text fields) are user interface controls that let users enter and edit short strings of text. They are a basic element of forms in websites and applications, used for names, search queries, email addresses, and other plain text data.

Most tekstfelter are single-line; multi-line text input is provided by a text area. In web development they are typically implemented with input elements of type text or with textarea elements. Browsers may offer built-in validation and input patterns; many frameworks provide higher‑level components that wrap these controls.

Key attributes include placeholder text, which shows a hint when the field is empty; maxlength and minlength to constrain length; required to enforce input; pattern for regular-expression validation; autocomplete to guide browser autofill; spellcheck; and autofocus on page load. Styling is usually done with CSS to control size, width, borders, and typography.

Accessibility requires a visible label tied to the control via the label element or aria-label. Focus, cursor, and error feedback should be perceivable to screen readers and keyboard users; error messages should be announced and paired with the field.

Security and privacy considerations include validating and sanitizing input on the server, not relying solely on client-side checks, and avoiding misuse of tekstfelter for sensitive data; use appropriate input types (for example password fields) when needed. Tekstfelter are a fundamental building block in data entry across platforms, including web, mobile, and desktop interfaces.
