Css reset all styles in div

The all shorthand CSS property resets all of an element’s properties except unicode-bidi , direction , and CSS Custom Properties. It can set properties to their initial or inherited values, or to the values specified in another cascade layer or stylesheet origin.

Try it

Constituent properties

This property is a shorthand for all CSS properties except for unicode-bidi , direction , and custom properties.

Syntax

/* Global values */ all: initial; all: inherit; all: unset; all: revert; all: revert-layer;

The all property is specified as one of the CSS global keyword values. Note that none of these values affect the unicode-bidi and direction properties.

Values

Specifies that all the element’s properties should be changed to their initial values.

Specifies that all the element’s properties should be changed to their inherited values.

Specifies that all the element’s properties should be changed to their inherited values if they inherit by default, or to their initial values if not.

Specifies behavior that depends on the stylesheet origin to which the declaration belongs:

If the rule belongs to the author origin, the revert value rolls back the cascade to the user level, so that the specified values are calculated as if no author-level rules were specified for the element. For purposes of revert , the author origin includes the Override and Animation origins.
If the rule belongs to the user origin, the revert value rolls back the cascade to the user-agent level, so that the specified values are calculated as if no author-level or user-level rules were specified for the element.
If the rule belongs to the user-agent origin, the revert value acts like unset .

Specifies that all the element’s properties should roll back the cascade to a previous cascade layer, if one exists. If no other cascade layer exists, the element’s properties will roll back to the matching rule, if one exists, in the current layer or to a previous style origin.

Formal definition

Initial value	There is no practical initial value for it.
Applies to	all elements
Inherited	no
Computed value	as the specified value applies to each property this is a shorthand for.
Animation type	as each of the properties of the shorthand (all properties but unicode-bidi and direction )

Formal syntax

all =
initial |
inherit |
unset |
revert |
revert-layer

Remove all styling with one line of CSS

Many times in your work as a frontend developer you had to create components with custom styles according to creative designs. The default styles of HTML elements like or are never the styles we want. The most common solution to this problem is to override the default styles, for example:

.reset  padding: 0; margin: 0; background: none; border: none; // and so on. >

Remove all styling

The all: unset CSS property resets all CSS properties to their initial or inherited values. This means that all properties will revert back to the values that were set in the user agent stylesheet or the values that were passed down from the parent element. By using all: unset , you can quickly and easily reset all the styles for a particular element, which can be useful in many situations. For example, you might use it to create a «reset» class that you can apply to an element when you want to remove all styles and start fresh.

Examples

You can then apply this class to an element when you want to remove all its styles:

 class="reset">This element has had its styles reset.

.override  all: unset; background-color: yellow; padding: 10px; >

In this example, you’re using all: unset to remove any styles that were previously applied to an element, and then applying your own styles (in this case, a yellow background and 10px padding).

.section  all: unset; display: flex; flex-direction: column; align-items: center; background-color: lightgray; padding: 20px; >

In this example, you’re using all: unset to remove all the styles for a section of a page, and then applying a new set of styles to create a custom layout.

All values of all property

The all property is a shorthand property in CSS that sets all of the CSS properties of an element to their initial or inherited values. The all property can take four values: initial , revert, inherit, and unset.

initial : sets all properties to their initial values. The initial value of a property is the value defined by the browser’s CSS stylesheet, or the default value defined in the CSS specification if there is no stylesheet. For example, setting the all property to initial on an element would reset all of its CSS properties to their default values.
revert : sets all properties to their inherited values. Inherited values are passed down from a parent element to its children. For example, if you set the color property of a parent element to red , and then set the all property of a child element to revert , the child element will inherit the color property from its parent and have a color of red .
inherit : sets all properties to the same values as the parent element. For example, if you set the color property of a parent element to red , and then set the all property of a child element to inherit , the child element will have the same color property as its parent and have a color of red .
unset : sets all properties to either their initial values (if they are not inherited) or their inherited values (if they are inherited). This value is similar to revert , but it also resets properties to their initial values if they are not inherited. For example, if you set the color property of a parent element to red , and then set the all property of a child element to unset , the child element will inherit the color property from its parent and have a color of red .

   class="initial">initial  class="revert">revert  class="inherit">inherit  class="unset">unset   unstyled

body  background-color: gray; padding: 20px; > div  display: flex; justify-content: center; color: white; gap: 10px; > button  width: 200px; height: 75px; margin: 10px; font-size: 18px; border: 2px solid black; > .initial  all: initial; background-color: lightgray; > .revert  all: revert; background-color: lightblue; > .inherit  all: inherit; background-color: lightgreen; > .unset  all: unset; background-color: lightpink; >

In summary, you can use the all property to reset all of the CSS properties of an element to their initial or inherited values, or to inherit all of the CSS properties from its parent element. The choice of which value to use depends on the specific use case and the desired behavior.

Caveats

There are some caveats to using all: unset , however. First, not all properties are fully reset by all: unset . Some properties, such as display , visibility , and float , are reset to their initial values, while others, such as padding and margin , are not reset at all. Additionally, some properties that are reset by all: unset may have unintended consequences, such as resetting the font size or the background color.

Browser compatibility

The use of the all property is widely supported by modern browsers and is not an issue for most current applications. The only notable exception is Internet Explorer and Opera Mini, which do not support this feature. Nevertheless, it is always advisable to test your code thoroughly in the browsers and devices you plan to target, to ensure that everything works as expected.

Summary

In summary, all: unset can be a useful tool for resetting styles, but it’s important to understand its limitations and to use it with caution.
