Click it, don't code it. Building with CSSexy feels like building with Lego.
Pick any HTML element, CSS property or SVG shape from a list of everything that works in all modern browsers, with every attribute and value it supports. CSSexy writes it in the right syntax for you, the preview shows you what you're building, and help right beside it explains how it works. You build, and you learn as you go.
Start from scratch, or paste code you already have and take it apart visually.
Bring your own code
Paste it in, see how it's built
Got HTML and CSS from ChatGPT, a component library, a Tailwind example or an old project? Paste it into Code import, click Apply, and it becomes an editable snippet.
Every element becomes a node in the HTML tree.
Every rule becomes a selector with real, editable properties.
SVG shapes, gradients, clip paths and masks come along too.
Shorthands, calc() and var() are understood, not flattened into text.
Before you apply, clean up with one click.
Remove Tailwind classes: keep the look, drop the utility classes.
Remove unused CSS: only keep rules the markup actually uses.
Simplify to Markdown: turn the text content into Markdown.
Where AI-generated UI becomes something you own
AI can generate an interface in seconds. Making it understandable, reusable and maintainable is the hard part. CSSexy bridges that gap.
Ask ChatGPT (or any AI) for a component.
Paste it into CSSexy.
Explore it visually and see how it works.
Restructure it, rename the classes, make it yours.
Copy the clean code into your project, or keep it in your snippet library.
Idea → understanding → production-ready code
One editor, many outputs
Whatever you're building, CSSexy knows the rules
Web components
Buttons, cards, layouts, icons, animations: anything HTML, CSS and SVG can do. Copy the result as one clean HTML document, or embed it.
Tailwind snippets
Prefer utility classes? Switch a snippet's stylepack to Tailwind CSS to
assign Tailwind classes to any HTML or SVG element.
use Tailwind theme variables in your own CSS.
@apply utility classes inside your selectors.
Mix Tailwind and your own classes freely, and see the result live.
HTML emails
Email is still stuck in the past: tables, inline styles and Outlook. Turn on Email mode and CSSexy does the remembering for you.
The CSSexy Editor only offers HTML and CSS that work in all major email clients (based on caniemail.com).
Partly supported properties get notes naming the clients that ignore them.
The Email preview shows the finished email with every style inlined, ready to copy and send.
A "Not in the email" report lists anything that was left out, and why.
A snippet can be anything from a button to a whole page. Put page snippets together and you get a booklet, a small site with rules of its own. Every page needs an address, readers need a way around, and every page should look like it belongs. CSSexy takes care of that too.
Clean URLs: every page in a booklet gets its own readable public address.
Table of contents: build the TOC as a snippet too, and choose on which pages it appears.
Pages from a template: start each new page from a template snippet, so the whole booklet shares one layout and one set of CSS.
Contributors: invite others to help you write and maintain it.
Write a guide, a tutorial series or a small documentation site, page by page.
Tool kit
Everything you need. Nothing you don't.
CSSexy covers all HTML elements, CSS properties and SVG features, with their attributes and valid values, so what you build can be beautiful, structured, accessible and user-friendly.
Visual editing, not setup overhead
Build HTML, CSS and SVG as trees.
Add, copy, move or delete single items or whole branches.
Edit every item in a form that only offers valid values.
See a live preview of the item and the whole snippet: at any device size, in split view next to the code, or as a full page.
Undo and redo every step.
"I can do that in VS Code." Sure, after the project setup, the tooling, and remembering every syntax rule and edge case. In CSSexy you click, edit and see the result immediately, on any device.
Smart helpers that actually help
Correct code, always: no missing brackets or commas; modern nested CSS output.
Classes: see every class in the snippet, and assign your own classes or Tailwind classes to HTML and SVG elements.
CSS variables: import, assign and manage your own variables and Tailwind's theme variables, right in the property you're editing.
Color picker: with modern colour formats and color-mix().
SVG inside HTML: nest an SVG straight into your markup.
Media library: upload images, video and audio once, pick them anywhere (Early Access feature).
Tidy Snippet CSS: drop the rules nothing uses anymore.
Learn while you build
Contextual help sits next to the fields it explains: from CSS background layers to ARIA roles and which email clients support what. You don't just build faster, you understand what you built.
