How to use
- Choose whether the accordion allows multiple panels open (Checkbox) or only one at a time (Radio).
- Adjust the open speed, header background color, and border color to taste.
- Type in the title and content for each accordion item, adding or removing items as needed.
- Check the live preview, then copy the HTML and CSS separately and drop them into your project.
FAQ
- Does it really work without JavaScript?
- Yes. The open/close behavior comes entirely from hidden checkbox/radio inputs paired with labels and CSS sibling selectors.
- What's the difference between multiple-open and single-open?
- Multiple-open (Checkbox) lets several items stay expanded at once, while single-open (Radio) keeps only one item open at a time.
- Can I paste the generated code into WordPress or a blog platform?
- Yes. Paste both the HTML and CSS together while in HTML editing mode and it will work the same way on most blog platforms.
