JavaScript Browser Detector

Highlight a browser logo using a small JavaScript user-agent detection example with five included icons.

What is included?

• Chrome, Firefox, Edge, Opera and Safari logos
• Plain JavaScript condition checks
• Local image assets

How to use the source

1. Download and extract the ZIP into a new folder.
2. Find index.html and keep its CSS, JavaScript and image folders beside it.
3. Open the example in a browser. For local development, you can use your editor’s local preview server.
4. Change the text, colors and links in your code editor, then test at desktop and mobile widths.

Before adding it to a website

User-agent detection is only a best-effort label and can be spoofed. Use feature detection when deciding whether a browser supports functionality.

Can I install this as a WordPress theme or plugin?

No. This download is standalone source code. To use a component in WordPress, scope its styles and add its scripts through a child theme or a small plugin. Uploading this ZIP through the WordPress theme or plugin installer will not turn it into an installable WordPress package.

Customization tips

Start with a copy of the original files. Replace sample text and placeholder links first, then adjust colors and spacing. Test keyboard navigation and narrow screens. For animation effects, provide a reduced-motion alternative before using them on a public site.
