CSS Accordion Generator

Content

Accordion content

Enter plain-text headings and panel content. HTML-like text is escaped in the generated code.

Your accordion text and settings stay in this browser tab. They are not sent through Livewire, placed in the URL, or uploaded. Closing the tab clears the saved funnel state.

Create a three-section accordion with semantic <details> and <summary> elements. Edit the plain-text headings and panels, choose the colors and spacing, preview keyboard behavior, then copy the escaped HTML and CSS or download a standalone file. The editor runs entirely in your browser tab.

How to create a CSS accordion

  1. 1

    Write three sections

    Add a short heading and plain-text panel for each item. HTML-like input is escaped rather than executed.

  2. 2

    Choose the design

    Set four six-digit colors, a corner radius from 0 to 24 px, and inner spacing from 8 to 32 px.

  3. 3

    Set the behavior

    Allow several panels to remain open or use the native `name` attribute for a single-open group. Pick a chevron or plus/minus indicator.

  4. 4

    Test and export

    Try the live preview with a pointer and keyboard, then copy the snippet or download a UTF-8 HTML file.

What the generator produces

Each item uses the browser’s native disclosure elements:

<details class="generated-accordion" open>
  <summary>What is included?</summary>
  <div class="generated-accordion__panel">Add the details here.</div>
</details>

The generated CSS styles the border, heading background, text, focus ring, spacing, corners and indicator. It uses logical properties such as margin-inline-start and includes right-to-left indicator rules. A reduced-motion media query removes the icon transition when the visitor requests less motion.

Multiple-open and single-open groups

Setting Generated markup Result
Several panels No shared name Every item toggles independently
One panel The same name="generated-accordion" on all items Opening one item closes another in browsers that support exclusive accordions

The single-open option relies on the native details name attribute. Older browsers that do not support exclusive groups still show a usable accordion, but may allow more than one item to stay open.

Safe plain-text content

Headings and panels are treated as text. Characters such as <, >, &, quotes and apostrophes are HTML-escaped in the exported snippet, so a pasted tag is displayed as text rather than becoming executable markup. If a panel needs links, lists or rich formatting, add that trusted markup yourself after exporting.

Accessibility checks before publishing

  • Tab to each summary and toggle it with Enter or Space.
  • Check the generated focus color against both the heading background and page background.
  • Keep headings concise and make the panel answer the heading clearly.
  • Test zoom, narrow screens and right-to-left pages in the destination layout.
  • Do not hide the page’s primary instruction inside a closed accordion.

Frequently Asked Questions

No. Opening and closing use native <details> and <summary> behavior. The downloaded component contains HTML and CSS only.

Yes, choose the single-open setting. The generator gives all three <details> elements the same name attribute. Browsers without support for exclusive details groups fall back to independent panels.

The editor intentionally treats input as plain text and escapes HTML characters. This prevents pasted markup from executing in the preview or generated snippet. Add reviewed rich markup after exporting if the project needs it.

No. Text, settings, preview, copy and download operations stay in the browser. During the multi-page funnel, temporary state is held in sessionStorage for the current tab and is not placed in the URL.
