Css remove style properties

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.

# Remove CSS Style Property from an Element

Use the style.removeProperty() method to remove CSS style properties from an element.

The removeProperty() method removes the provided CSS style property from the element.

Here is the HTML for the examples.

Copied! 
DOCTYPE html> html lang="en"> head> title>bobbyhadz.comtitle> meta charset="UTF-8" /> head> body> div id="box" style="background-color: yellow; color: red; width: 100px; height: 100px" > Box 1 div> script src="index.js"> script> body> html> 

And here is the related JavaScript code.

Copied! 
const box = document.getElementById('box'); // ✅ Remove CSS properties box.style.removeProperty('width'); box.style.removeProperty('height'); box.style.removeProperty('background-color'); // ✅ Set CSS Properties // box.style.setProperty('background-color', 'salmon'); 

We used the style.removeProperty method to remove CSS properties from the element.

# Adding a CSS style property to an element

If you need to add a CSS style property to the element, use the style.setProperty method.

Copied! 
const box = document.getElementById('box'); // ✅ Set CSS Properties box.style.setProperty('background-color', 'salmon'); 

The style.setProperty method sets or updates a CSS style property on the DOM element.

Alternatively, you can use a more direct approach.

# Remove a CSS style property from an element by setting it to null

You can also remove CSS style properties from an element by setting the property to a null value, e.g. box.style.backgroundColor = null; .

When an element’s CSS property is set to null , the property is removed from the element.

Copied! 
const box = document.getElementById('box'); // ✅ Remove CSS properties box.style.backgroundColor = null; box.style.width = null; // ✅ Set CSS Properties // box.style.backgroundColor = 'coral'; 

We can access CSS properties on the element’s style object.

Notice that instead of hyphenating property names, we use camel-cased names when using this approach, e.g. backgroundColor instead of background-color .

The style object allows us to read, set, and update the values of CSS properties on the element.

If you want to set a CSS property on the element, set the property to a value other than null .

Copied! 
const box = document.getElementById('box'); // ✅ Set CSS Properties box.style.backgroundColor = 'coral';

Превращаем круг в квадрат.

 const circle = document.getElementById('round'); function turnToSquare ()  circle.style.removeProperty('border-radius');> const circle = document.getElementById('round'); function turnToSquare ()  circle.style.removeProperty('border-radius'); >    Скопировать Скопировано Не удалось скопировать   

Как пишется

remove Property ( ) принимает один аргумент – строку с именем свойства. Пишем названия также, как в CSS: background — color , а не background Color .

 vampire.style.removeProperty('box-shadow'); vampire.style.removeProperty('box-shadow');    Скопировать Скопировано Не удалось скопировать   

Как понять

Метод remove Property ( ) позволяет удалить отдельное CSS-свойство элемента.

Чтобы управлять отображением элемента лучше использовать чистый CSS, устанавливая элементу классы-модификаторы с нужным набором стилей.

Но иногда полезно программно изменять CSS-свойства. Например, если в нужный момент установить элементу свойство will — change , а потом удалить его, то можно получить выигрыш по производительности.

Если с помощью метода remove Property ( ) не выходит удалить свойство и вы получаете ошибку «NoModificationAllowedError» – значит элемент или его свойство находится в режиме read — only .

Есть альтернатива – можно использовать style и указать свойству значение «null». Названия в этом случае пишем через camelCase:

 vampire.style.boxShadow = null; vampire.style.boxShadow = null;    Скопировать Скопировано Не удалось скопировать

Как удалить CSS-свойство?

Добрый день, нужно удалить CSS свойство, как это можно сделать?

Хочу удалить left: 0; и поставить right: 0;

Как это можно реализовать?

p.s если поставить просто right: 0; то объект читает left и забивает на right.

Егор Рублёв: Встречный вопрос: а зачем? Вы просто сбрасываете свойство на значение по умолчанию и получаете эффект, как будто бы и не устанавливали его.

С любыми свойствами так. Смотрите в доках, какое стоит значение по умолчанию, и ставите его.
Initial — штука интересная, но пока не работает везде.

Сергей: ну мне в принципе нет разницы, а вот лишний код же на выходе будет?
left: auto; = 11 символов, да и не люблю грязь.

Сброс конкретного свойства установленного через element.style.property или через атрибут style в html:

element.style.property = void 0; //void 0 - это оператор возвращающий безопасный undefined

А вообще лучше не устанавливать свойства через атрибут style или через element.style (что равносильно), манипулируйте классами
