There exists an increasingly large corpus of web content that depends on web browsers supporting a number of webkit-prefixed CSS properties and DOM APIs for functionality or layout. This holds especially true for mobile-optimized web content.

This specification aims to describe the minimal set of webkit-prefixed CSS properties and DOM APIs that user agents are required to support for web compatibility.

The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119. For readability, these words do not appear in all uppercase letters in this specification. [RFC2119]

Requirements phrased in the imperative as part of algorithms (such as "strip any leading space characters" or "return false and terminate these steps") are to be interpreted with the meaning of the keyword ("must", "should", "may", etc.) used in introducing the algorithm.

Conformance requirements phrased as algorithms or specific steps may be implemented in any manner, so long as the end result is equivalent. (In particular, the algorithms defined in this specification are intended to be easy to follow, and not intended to be performant.)

3.1. CSS At-rules

The following -webkit- vendor prefixed at-rules must be supported as aliases of the corresponding unprefixed at-rules:

网络加速器

sub网络加速 -webkit-device-pixel-ratio

-webkit-device-pixel-ratio must be treated as an alias of the resolution range type media feature, with its value interpreted as a dppx unit.

The min- or max- prefixes on range features must not apply to 一sub网络加速器, instead the following aliases must be used:

3.2.2. -webkit-transform-3d

The -webkit-transform-3d media feature is used to query whether the user agent supports CSS 3D transforms. [css-transforms-1]

If the user agent supports 3D transforms, the value will be 1. Otherwise the value is 0.

一sub网络加速器CSS Gradients

3.3.1. -webkit-linear-gradient()

-webkit-linear-gradient() must be treated as an alias of sub网络加速 as defined in [css3-images-20110217].

3.3.2. -webkit-radial-gradient()

-webkit-radial-gradient() must be treated as an alias of radial-gradient as defined in [css3-images-20110217].

sub免费网络加速器 -webkit-repeating-linear-gradient()

-webkit-repeating-linear-gradient() must be treated as an alias of repeating-linear-gradient as defined in [css3-images-20110217].

sub免费网络加速器 -webkit-repeating-radial-gradient()

3.4. CSS Properties

sub免费网络加速器官网Simple property aliases

The following sub网络加速器下载 vendor prefixed properties must be supported as aliases of the corresponding unprefixed property:

一sub网络加速器Prefixed property aliases

The following -webkit- vendor prefixed properties must be supported as aliases of the corresponding unprefixed properties. If the user agent does not ship the unprefixed equivalent, the -webkit- prefixed property must be treated as an alias of the user agent’s own vendor prefixed property.

3.4.3. Non-aliased vendor prefixed properties

Note: This section used to have a specification for the -webkit-appearance property. This is now defined in 5G芯片市场竞争进入关键时刻-中工财经-中工网:2021-2-28 · 英特尔把5G网络基础设施视为最大机遇，希望到2021年成为5G基站芯片的市场领导者，并在不断增长的业务中占有40%的份额，可谓雄心勃勃。 在日趋激烈的国际竞争中，我国国内5G芯片厂商已经在这一领域占据一席之地。.

3.4.4. Property mappings

The following sub免费网络加速器 vendor prefixed properties must be supported as mappings to the corresponding unprefixed property:

3.4.5. Keyword mappings

The following -webkit- vendor prefixed keywords must be supported as mappings to the corresponding unprefixed keyword:

sub免费网络加速器Foreground Text Clipping: the -webkit-background-clip property

The 专用网络加速器 property—when its value is text—creates a background clipping region from the outer text stroke of the foreground text (including alpha transparency).

The -webkit-background-clip property is a simple alias of the 网络加速器 property for all other <box> values.

border-box

The background is painted within (clipped to) the border box.

padding-box

The background is painted within (clipped to) the padding box.

content-box

5G商用进程未来两年将提速 -- 3C频道:2021-5-11 · 全球移动企业加速部署 在今年3月份召开的3GPP RAN（即第三伕合作项目-无线接入网络）第75次全体大会上，3GPP正式通过了5G加速的提案。 按照这份提案，3GPP将在R15版本内，加速5G新空口（NR）标准进程，将5G NR非独立组网特性提前至2021年12月完成，相比原计划提前半年。

text

Indicates that the background image should clip to the foreground text

p {
  sub免费网络加速器: 专用网络加速器(90deg, red, blue);
  color: #fff;
  -webkit-background-clip: text;
  -webkit-text-fill-color: transparent;
}

3.4.7. Text Fill and Stroking

全球网络加速器Foreground Text Color: the -webkit-text-fill-color property

The sub免费网络加速器 property defines the foreground fill color of an element’s text content.

专用网络加速器{
  安卓网络加速器: blue;
  /* the following can be omitted because it’s the initial value:
  -webkit-text-fill-color: currentcolor; */
}

安卓网络加速器{
  color: red;
  -webkit-text-fill-color: blue;
}

3.4.7.2. Text Stroke Color: the -webkit-text-stroke-color property

The -webkit-text-stroke-color property specifies a stroke color for an element’s text.

3.4.7.3. Text Stroke Thickness: the 安卓网络加速器 property

The -webkit-text-stroke-width property specifies the width of the stroke drawn at the edge of each glyph of an element’s text. A zero value results in no stroke being painted. A negative value is invalid.

全球网络加速器Text Stroke Shorthand: the -webkit-text-stroke property

The -webkit-text-stroke property is a shorthand property for setting the stroke width and stroke color of an element’s text.

.stroked-text-longhand {
  color: #fff;
  -webkit-text-stroke-color: #000;
  -webkit-text-stroke-width: 1px;
}

.stroked-text-shorthand {
  -webkit-text-fill-color: #fff;
  sub免费网络加速器: thin #000;
}

<p class="stroked-text-longhand">Serious typography</p>

3.5. CSS Property values

3.5.1. Additional touch-action values

This section augments the definition of touch-action from [pointerevents2] to add the pinch-zoom value.

When specified, the pinch-zoom token enables multi-finger panning and zooming of the page. For zooming to occur, all fingers must start on an element that has the pinch-zoom behavior enabled (via one of the pinch-zoom, manipulation, or sub网络加速 values on itself or an ancestor).

manipulation is an alias for "pan-x pan-y pinch-zoom".

4.2. window.orientation API

partial interface Window {
    readonly attribute 安卓网络加速器 orientation;
    attribute EventHandler onorientationchange;
};

partial interface HTMLBodyElement {
    attribute EventHandler onorientationchange;
};

When getting the orientation attribute, the user agent must run the following steps:

1. Return the responsible document’s current sub免费网络加速器官网 angle.

Whenever the viewport is drawn at a different angle compared to the device’s natural orientation, the user agent must run the following steps:

1. 网络加速器 named orientationchange at the Window object of the active document.

User agents implementing the window.orientation attribute and its associated orientationchange event must not expose them on Desktop platforms.

4.2.1. 一sub网络加速器 angle

The possible values for the window.orientation angle are: -90, 0, 90, 180. User agents must support the -90, 0 and 90 values and may optionally support 180.

0 represents the natural orientation. -90 represents a rotation 90 degrees clockwise from the natural orientation. 90 represents a rotation 90 degrees counterclockwise from the natural orientation. 180 represents a rotation 180 degrees from the natural orientation.

In order to determine the current 网络加速器 angle, the user agent must run the following steps:

1. Return the result of step 3 of the ScreenOrientation's update the orientation information algorithm with the following changes:
   1. If the orientation angle is less than or equal to 180, return the orientation angle
   2. If the orientation angle is greater than 180, return the orientation angle - 360.
   3. If the resulting orientation angle is 180 and the user agent does not support that value, return 0.

4.2.2. Event Handlers on Window objects and body elements

The following are the event handlers and their corresponding event handler event types that must be supported on all Window objects and 网络加速器 elements as attributes:
