Widgets snippets for WordPress
Snippets for widgets and sidebars: restore the classic widget screen, register new widget areas, remove default widgets and allow shortcodes in text widgets. For classic themes and sites that still lean on sidebars.
Sidebar Widgets as Cards (SCSS)
Styles each sidebar widget as a card with a border, rounded corners, an underlined title and tidy list dividers.
Tag Cloud as Pills (SCSS)
Restyles the Tag Cloud widget and block as a tidy row of rounded pills with equal font sizes, which reads better than a jumble of sizes.
