Easy Custom JS and CSS for WordPress

Many sites need small changes that a theme or plugin does not offer: a style tweak, a short script, a bit of extra markup. Editing theme files is risky, because an update can wipe out your work. Easy Custom JS and CSS for WordPress keeps your code separate, so the changes stay in place after theme and plugin updates.

The plugin gives you a code editor with syntax highlighting inside the WordPress dashboard. A filter system then controls where each piece of code runs. You can target specific pages, posts, devices, browsers, operating systems, or set a date and time. That suits mobile-only styles or a script for a short campaign period. It fits owners, designers and developers who want precise control over small customizations.

Features

• Code editor with syntax highlighting: Write and edit JavaScript, CSS and HTML directly inside WordPress. Syntax highlighting makes the code easier to read and helps you spot mistakes while you work.
• Advanced filter builder: Build rules that apply your code to specific URLs, posts, pages, devices, browsers, operating systems, or custom conditions such as date and time.
• Separate JS, CSS and HTML inputs: Manage JavaScript, CSS and HTML independently. Keeping each type of code apart makes your customizations more organized and easier to maintain or troubleshoot.
• Flexible injection locations: Embed your code inline or load it as an external file. You can also place scripts and styles in the header or the footer of the page.
• Safe theme and plugin customization: Change the styles and behavior of your site without editing theme or plugin files, so your custom code remains intact after updates.
• Device and browser targeting: Run custom code only on the devices or browsers you choose, which lets you deliver tailored styles or scripts to different visitors.
• Scheduled code execution: Set JavaScript and CSS to become active on specific dates or times. This works well for time-sensitive promotions or seasonal design changes.
• Lightweight design: The plugin is built to be light, so adding custom code does not weigh down your WordPress installation with unneeded extras.

Best for

• Site owners who want small tweaks without editing theme files
• Developers and designers managing custom code across client sites
• Sites running time-limited campaigns or device-specific styling
