Vendor prefixes [other than `ms`](http://www.andismith.com/blog/2012/02/modernizr-prefixed/) should begin with a capital letter. This is why `WebkitTransition` has an uppercase "W". -When specifying a pixel value for your inline style prop, React automatically appends the string "px" for you after your number value, so this works: +React will automatically append a "px" suffix to certain inline style properties. For example: ```js -const divStyle = { - height: 10 // rendered as "height:10px" -}; - -function HelloWorldComponent() { - return
Hello World!
; -} +// This: +
+ Hello World! +
; + +// Becomes: +
+ Hello World! +
``` -Sometimes you _do_ want to keep the CSS properties unitless. Here's a list of properties that won't get the automatic "px" suffix: - -- `animationIterationCount` -- `boxFlex` -- `boxFlexGroup` -- `boxOrdinalGroup` -- `columnCount` -- `fillOpacity` -- `flex` -- `flexGrow` -- `flexPositive` -- `flexShrink` -- `flexNegative` -- `flexOrder` -- `fontWeight` -- `lineClamp` -- `lineHeight` -- `opacity` -- `order` -- `orphans` -- `stopOpacity` -- `strokeDashoffset` -- `strokeOpacity` -- `strokeWidth` -- `tabSize` -- `widows` -- `zIndex` -- `zoom` - -See [unitless properties](https://github.com/facebook/react/blob/4131af3e4bf52f3a003537ec95a1655147c81270/src/renderers/dom/shared/CSSProperty.js#L15-L59) for more examples. +Not all style properties are converted to pixel strings though.
