Understanding CSS all

The CSS all property resets all properties except unicode-bidi, direction, and CSS custom properties. As part of the Misc module in CSS, it is one of the most commonly used properties for controlling the visual presentation of web pages.

You can set all to values such as initial, inherit, unset, revert, among others. Each value changes how the browser renders the affected element, giving you fine-grained control over your page layout and design. Choosing the right value depends on the specific design requirements of your project.

Common use cases for the all property include responsive web design, component-based layouts, and creating visually consistent interfaces across devices. It works closely with related properties like display, color, font to achieve complex styling effects. Understanding how these properties interact helps you write cleaner, more maintainable stylesheets.

Browser support for all is excellent across all modern browsers including Chrome, Firefox, Safari, and Edge. For older browsers, consider using fallback values or progressive enhancement strategies. The property can also be set dynamically via JavaScript using element.style.all or the CSS custom properties (variables) approach for theming.
