- initial — сбрасывает все свойства элемента до дефолтных, описанных в спецификации.
- inherit — элемент будет наследовать все стили родителя, даже те, которые обычно не наследуются.
- unset — элемент наследует все наследуемые стили родителя, а остальные сбрасывает до дефолтных.
- revert — действие зависит от источника стилей: браузер, пользователь или сайт.

Для начала создадим базовый блок с контентом.
Предисловие о многоножках.div class="container"> span>Предисловие о многоножках. span> p class="paragraph"> p> div>
.container font-size: 30px;>.container font-size: 30px; >
Сбросим у параграфа стили при помощи: all : initial; . Ещё зададим color : white; , иначе цвет текста сбросится до чёрного и текст станет не читаем на тёмном фоне.
.paragraph all: initial; color: white;>.paragraph all: initial; color: white; >
Все значения сбросились до дефолтных. Больше всего бросаются глаза изменения font — family , font — size , display .

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.
