У all 4 возможных значения:

• 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.

Значение revert

Действие значения revert зависят от источника стилей.

1. Браузерные стили: действие аналогично unset .
2. Пользовательские стили: откатываемся по каскаду к браузерным стилям (словно пользовательских для этого свойства не существует).
3. Авторские стили: откатываемся по каскаду к пользовательским стилям (словно авторских для этого свойства не существует).

   Предисловие о многоножках.   div class="container"> span>Предисловие о многоножках. span> p class="paragraph"> p> div>    Скопировать Скопировано Не удалось скопировать   

 .container  font-size: 30px;> .container  font-size: 30px; >    Скопировать Скопировано Не удалось скопировать   

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; >    Скопировать Скопировано Не удалось скопировать   

Все значения сбросились до дефолтных. Больше всего бросаются глаза изменения font — family , font — size , display .

How to clear all css styles

I’m creating a snippet of HTML to allow others to add functionality to their web sites (it is a voting widget). I’ve created a snippet of HTML like this:

 
[implementation of my voting widget]
 

I spent a lot of time to get the formatting of this widget just right. It works great in a sample web page that does not import a style sheet.

When I add the widget to a page on a Drupal site, however, the imported CSS wreaks havoc with my careful formatting. I’d like my HTML snippet to ignore all CSS style sheets. Is this possible?

Regardless of whether it is possible, is there a better solution?

Instead of relying on your CSS styles not being overridden by any imported stylesheets, you should give your widget a unique id and make sure all of your styles are a derivative of that id making sure to implement any styles you don’t want to be overriden ( margin , padding , etc):

 
 #votify <> #votify ul <> #votify div span <> /* etc */ 

You could try using a reset stylesheet:

Of course, you don’t want to overwrite the page’s CSS but you can get an idea on how to reset the styles your widget uses and use your personal CSS. So something like.

Reset your widget css to default values, and THEN add your formatting code. This will clear out any page styles so you can work from a clean slate.

Without using a style sheet I think you’d have to explicitly set all margins, padding, fonts, etc in the style attribute so it takes precedence over any CSS sheets that there are.

Art History Final — The Clear Line Style of Art

This is my final for art history. It is a video presentation answering the essential question: Does the clear line style of art affect us and if so, how?

Remove a specific inline style with Javascript|jQuery

I have the following code in my html:

and that in my external css:

I want to remove all font-size and font-family in the style atribute, but not the color and others set in external css.

Result expected:

Already tried:

$('#foo').removeAttr('style'); // That removes all inline $('#foo').css('font-family',''); // That remove the css setted too 

For those that aren’t using jQuery, you can delete specific styles from the inline styles using the native removeproperty method. Example:

elem.style.removeProperty('font-family'); 

elem.style.removeAttribute('font-family'); 

so a cross browser way to do it would be:

if (elem.style.removeProperty) < elem.style.removeProperty('font-family'); >else

Set the properties to inherit :

$('#foo').css('font-family','inherit').css('font-size','inherit'); 

I think there is no proper solution to this problem (without changing your markup). You could search and replace the style attribute’s value:

var element = $('#foo'); element.attr('style', element.attr('style').replace(/font-size:[^;]+/g, '').replace(/font-family:[^;]+/g, '')) 

By far the best solution would be to get rid of the inline styles and manage the styles by using classes.

In 2019, the simplest way to remove a property seems to be:

Similarly, to set a border:

elem.style.outline = "1px solid blue"; 

Should work across all browsers too!

CSS line-break Property

The line-break property specifies how to break lines of Chinese, Japanese, or Korean text working with punctuation and symbols. But, these languages have different rules. This line break might not occur. For example, if the value is set to «strict», break before hyphens are not allowed in Chinese and Japanese languages.

The CSS specification emphasizes rules only for Chinese, Japanese and Korean.

For maximum browser compatibility extensions such as -webkit- for Safari, Google Chrome, and Opera (newer versions), -moz- for Firefox, -o- for older versions of Opera are used with this property.
