Chrome 135 introduces native styling capabilities for HTML select elements through the new appearance: base-select CSS property. This eliminates the need for custom dropdown libraries by enabling complete control over select buttons, dropdown pickers, icons, and options. Developers can now style selected content, add rich media to options, customize checkmarks, and apply conditional styling using new pseudo-elements like ::picker(), ::picker-icon, and ::checkmark. The feature is currently supported only in Chromium-based browsers.
