Snippets

Custom Code Snippets for Enhanced Visuals and Functionality

This bundle includes a variety of ready-to-use code snippets that enhance the appearance and functionality of your website. The codes range from basic visual improvements like background color changes and button styling to more advanced effects such as animated preloaders, floating panels, and interactive wizards.

Each snippet is lightweight, customizable, and works without external libraries. They are ideal for web designers and developers who want more control over visual presentation and UX, without relying on heavy plugins.

Integration

All snippets are designed to work across modern WordPress setups. You can integrate them in two main ways:

1. For visual styling (backgrounds, buttons, fonts, shadows, etc.):

✓ Use the built-in “Additional CSS” field in the WordPress Customizer (Appearance → Customize → Additional CSS).
✓ Or inject the CSS using HFCM (Header Footer Code Manager) as a style block.
✓ Make sure the element selectors match your theme (you can adjust .my-button, body, section, etc.).

2. For animations, preloaders, and dynamic UI (JS or HTML+CSS based):

✓ Paste the <script> and <style> code into HFCM, or a plugin like Code Snippets.
✓ For snippets that require HTML containers (e.g. loaders or widgets), insert them into your theme using HTML blocks, widget areas, or custom templates.
✓ Always place JavaScript after the DOM loads – either at the footer or inside a DOMContentLoaded wrapper.

3. Universal recommendations:

✓ Snippets are modular – include only what you need.
✓ All styles are fully customizable: you can change sizes, spacing, color schemes, and timing.
✓ Compatible with most themes and page builders (Elementor, Gutenberg, Blocksy, Astra, etc.).
✓ No special setup required – just copy, paste, and tweak.
