All tools › The page, not the box
Flexbox
Every property that does something, drawn, with the sentence that makes the two axes make sense.
It runs entirely in this browser tab: the CSS you paste is never uploaded, and the preview is drawn from the same numbers the rule carries rather than rendered by the browser — which is why a tool whose effect only exists in a compositor says so instead of drawing one.
Settings
- Direction
- Choices: Across, Across, backwards, Down, Up.
- Along the main axis
- Choices: At the start, At the end, Centre, Space between them, Space around each, Space evenly.
- Across the other axis
- Choices: Filling the space, At the start, At the end, Centre, Along the text baseline.
- Wrapping
- Choices: Never wrap, Wrap onto more lines, Wrap upwards.
- Gap
- A number from 0 to 120.
- Items
- How many boxes to draw, which changes nothing about the rule. A number from 1 to 12.
How to use it
- Paste your text into the box above, or open a file.
- Adjust the settings beside it until the result is what you wanted.
- Copy the result, or save it as a file. The result updates as you type.
Questions
- Is what I paste uploaded anywhere?
- No. The whole application is carried as WebAssembly and runs on your own device. There is no server to send a stylesheet to, and no tool here makes a network request while it works.
- Is the preview what my browser will actually draw?
- For a colour, a shape and a curve, yes — it is drawn from the same numbers the rule carries. For anything a browser's compositor does against the page behind it — a backdrop filter, a blend mode, a scrollbar — no, and that tool says so on its own result rather than showing you an approximation.
- Why does a size come out as 1.125rem and not 1.1250000000000002rem?
- Because none of the arithmetic is done in binary floating point. Every length here is an exact decimal, so a conversion ends where it should: 18px is 1.125rem and 24px is 18pt, with no run of nines and no stray four at the twelfth place.
- Can I use these rules without attribution?
- Yes. What comes out is CSS — a declaration is not a work with an owner, and nothing here writes a comment into your stylesheet about where it came from.
