Cross-browser CSS for consistent select element styling.

Demo page:

Download: select-css.css and select-css-compat.css

Available on npm: npm install fg-select-css

If you’re looking for the JS version of the select plugin, check out select.


Include some or all of the following files, picking and choosing based on your project needs:

  • select-css.css: main component code (required)
  • select-css-arrow.css: adds a CSS triangle arrow to the wrapper element. Don’t include this file and style .custom-select::after yourself to customize your own arrow. Could use a background image bitmap, SVG, icon font content, etc.
  • select-css-compat.css: expanded B-Grade browser support (see more info below).
  • select-css-theme.css: include the Filament Group theme with custom focus styling.

How it works

This styles a native select consistently cross-platform with only minimal CSS. The native select is then styled so it is essentially invisible (no appearance, border, bg) leaving only the select's text visible. There is a wrapper around the select that has the majority of the button styles (gradient, shadow, border, etc.).

There are three different CSS-only grades used in this select plugin:

  1. A-grade: Uses custom pseudo-element arrow and hides the native arrow using appearance: none (or a compatible vendor prefixed property).
  2. B-grade: Uses a custom pseudo-element arrow but hides the native arrow by making the native select wider than the container (usually using calc() to keep 100% width but add a fixed amount) and hiding the arrow using overflow: hidden.
  3. C-grade: Uses the native select and not the custom arrow.

Both A-Grade and B-grade visually look the same:

A and B-Grade select-css

C-Grade appearance varies by operating system and web browser.

Important: The plugin should never show both the custom arrow and the native arrow at the same time. Any browser that renders both will be considered to be a visual bug and we’d love to have you file an issue on it.
