What is sx in css?

The sx prop lets you style elements inline, using values from your theme. To use the sx prop, add the custom /** @jsxImportSource theme-ui */ pragma comment to the top of your module or configure automatic JSX runtime in your transpiler.

The sx prop lets you add any valid CSS to an element, while using values from your theme to keep styles consistent. You can think of the style object that the sx prop accepts as a superset of CSS.

The following CSS properties will use values defined in the theme, when available.

Theme UI also supports CSS Logical Properties, which follow this structure:

Theme UI, like Styled System, includes a shorthand syntax for writing mobile-first responsive styles using arrays as values. This is useful when you want to change a single property across multiple breakpoints without needing to write verbose media query syntax.

With responsive arrays, the 0-th element maps to all breakpoints, and the n-th element maps to the (n - 1)-th breakpoint. For example:

If you want to skip a breakpoint, you can use the value null. This is useful if you want to set a value for only the largest breakpoint, for example.

If you prefer standard CSS media query syntax, you can use nested objects for responsive styles as well.

Margin and padding are treated as first-class citizens in Theme UI, using values defined in the theme.space scale, and include an optional shorthand syntax for using negative space in your application.

In addition to shorthands for applying margin and padding on the x- and y-axes, a terse naming convention can be used to quickly edit styles.

For shorthand CSS properties or ones that are not automatically mapped to values in the theme, use an inline function to reference values from the theme object.

In some cases you might want to apply styles to children of the current element. You can do so with Emotion's nested selectors.

If you want to reference the current class selector of the component, such as for psuedo-classes & psuedo-elements, you can use the & symbol.

To opt-out of using theme-based CSS, use the css prop to render raw CSS values.

Because MDX uses its own custom pragma and createElement function, the Theme UI pragma will not work in MDX files. You can use any of the Theme UI components, which support the sx prop, in an MDX file as a workaround.

If you're new to using JavaScript object notation for authoring styles, see the guide to using objects for styling.

The sx prop is a shortcut for defining custom styles that has access to the theme. The sx prop lets you work with a superset of CSS that packages all of the style functions exposed in @mui/system . You can specify any valid CSS using this prop, as well as many theme-aware properties that are unique to MUI System.

The border property can only receive a number as a value. It creates a solid black border using the number to define the width in pixels:

The borderColor property can receive a string, which represents the path in theme.palette:

The borderRadius property multiplies the value it receives by the theme.shape.borderRadius value (the default for this value is 4px).

The displayPrint property allows you to specify a CSS display value that will only be applied when printing:

The CSS Grid properties gap, rowGap and columnGap multiply the values they receive by the theme.spacing value (the default for the value is 8px).

The color and backgroundColor properties can receive a string, which represents the path in theme.palette:

The backgroundColor property is also available through its alias bgcolor:

Read more on the Palette page.

The zIndex property maps its value to the theme.zIndex value:

Read more on the Positions page.

The boxShadow property maps its value to the theme.shadows value:

The sizing properties width, height, minHeight, maxHeight, minWidth, and maxWidth use the following custom transform function for the value:

If the value is between [0, 1], it's converted to a percentage. Otherwise, it is directly set on the CSS property:

Read more on the Sizing page.

The spacing properties margin, padding, and the corresponding longhand properties multiply the values they receive by the theme.spacing value (the default for the value is 8px):

The following aliases are available for the spacing properties:

Read more on the Spacing page.

The fontFamily, fontSize, fontStyle, fontWeight properties map their value to the theme.typography value:

The same can be achieved by omitting the CSS property prefix fontWeight:

There is an additional typography prop available, which sets all values defined in the specific theme.typography variant:

Read more on the Typography page.

All properties associated with the sx prop also support responsive values for specific breakpoints.

Read more on the Usage page—Responsive values.

Each property in the sx prop can receive a function callback as a value. This is useful when you want to use the theme for calculating a value:

The sx prop can also receive a callback when you need to get theme values that are objects:

Array types are useful when you want to partially override some styles in the former index:

When you hover on this element, color: red; backgroundColor: white; is applied.

If foo: true, then color: red; backgroundColor: grey; is applied when hovering.

If bar: true, then color: red; backgroundColor: yellow; is applied when hovering regardless of foo value, because the higher index of the array has higher specificity.

If you have ever looked at your medical chart, your doctor’s notes may look like “chicken scratch.” To make noting things faster when you’re talking to your doctor, they use a series of abbreviations for bigger words to make sure all the information gets into your chart. To help you understand better what your doctor has written, we have compiled a list of medical abbreviations and what they mean. You will find the SX medical abbreviation meaning and a few more of the most common ones used in charts. Read on to see what all of this jargon means.

The abbreviation is for the word symptoms. If you see it written “s/sx” it is the shortened term for “signs and symptoms” of a certain condition or disease. Since the first paragraph in a doctor’s examination notes can contain a lot of information, frequently used words like “symptoms” are shortened to make room for the most important words, the actual symptom. You will notice how the letter “x” is used after the first letter of each, which makes charting and documentation even faster for busy medical professionals.

There are many words in medicine that are used over and over, so doctors will use abbreviations to lessen the amount of writing they have to do. More of these include:

GXT

There are many more abbreviations used in the medical field that do not contain the “x.” Some of these that are used often in medical charts include:
