Buttonprimary

Buttonprimary is a class name used in web development to designate the primary action button within a user interface. It is not an HTML element or a browser standard; rather, it is a CSS class that developers apply to button, input type="button", or anchor elements to signal emphasis and action priority. The naming convention buttonprimary is one of several schemes used in custom projects and design systems; more common alternatives include btn-primary or primary.

In practice, a button marked as primary usually uses higher contrast and stronger emphasis than secondary actions to draw the user's attention. It typically represents the recommended next step on a page and should be used sparingly to avoid visual fatigue. States commonly include default, hover, active, focus, and disabled; accessible contrast and clear focus indicators are essential to ensure keyboard and screen reader users can identify the primary action.

Implementation examples show its use with standard HTML elements and CSS styling. Example: HTML: <button class="buttonprimary">Submit</button> CSS: .buttonprimary { background-color: #0d6efd; color: #fff; border: 1px solid #0d6efd; padding: .5em 1em; border-radius: .25em; } .buttonprimary:hover { background-color: #0b5ed7; } .buttonprimary:focus { outline: 3px solid rgba(13,110,253,0.5); outline-offset: 2px; }

Design systems may provide tokens for color, typography, and spacing, allowing buttonprimary to adapt to themes while preserving semantics. See also btn-primary, primary button, design system principles.
