Horizontally Clipped by OverflowĪn outcome is a conclusion that comes from evaluating an ACT Rule on a test subject or one of its constituent test target. Note that when an IDL attribute reflects a content attribute, they have the same attribute value. The attribute value of an IDL attribute is the value returned on getting it. This list is not exhaustive, and only serves as an illustration for some of the most common cases.
CSS SPAN TEXT OVERFLOW ELLIPSIS CODE
For attributes that accept numbers, the attribute value is the result of parsing the value written in the HTML code according to the rules for parsing this kind of number.For attributes whose value is used in a case-insensitive context, the attribute value is the lowercase version of the value written in the HTML code.Thus, and all have a disabled attribute value of true.
For boolean attributes, the attribute value is true when the attribute is present and false otherwise.Thus has an attribute value of either Image Button (the state) or image (the keyword mapping to it), both formulations having the same meaning similarly, "an input element with a type attribute value of Text" can be either, (missing value default), or (invalid value default). For enumerated attributes, the attribute value is either the state of the attribute, or the keyword that maps to it even for the default states.Some notable case of attribute value, among others: It may differ from the value that is actually written in the HTML code due to trimming whitespace or non-digits characters, default values, or case-insensitivity.
The attribute value of a content attribute set on an HTML element is the value that the attribute gets after being parsed and computed according to specifications. G42: Using a technology that has commonly-available user agents that support zoom.Understanding Success Criterion 1.4.4: Resize text.CSS specifications recommend that the used value is between 1.0 and 1.2 and major browsers are effectively using values close to 1.2. When the computed value of the line-height property is normal, the used value depends on font specific metrics. Some user agents treat the value of the aria-hidden attribute as case-sensitive. A 1280 by 1024 viewport size is explicitly mentioned under success criterion 1.4.10 Reflow. While success criterion 1.4.4 Resize text does not explicitly mention which viewport size has to be resized up to 200%, it is assumed that a viewport size of 1280 by 1024 is applicable.Text nodes can not be horizontally or vertically clipped by overflow without loss of information, except for text nodes with an ancestor with aria-hidden set to true, or when specific styles have been applied to ensure text is clipped cleanly (text-overflow, line wrapping or hidden text).This includes font resizing in the browser, or a javascript mechanism of resizing in the page. There is no other mechanism for resizing text available on the page, that can be used to resize text to 200% without loss of information or functionality.If any of the following assumptions is true, failing this rule may not result in a failure of success criterion 1.4.4 Resize text: Expectation 1Įach test target is not horizontally clipped by overflow of an ancestor in the flat tree when in a viewport size of 640 by 512, except if the clipping ancestor has a computed white-space of nowrap, and a computed text-overflow that is not clip Expectation 2Įach test target is not vertically clipped by overflow of an ancestor in the flat tree when in a viewport size of 640 by 512, except if the clipping ancestor has a used line-height equal to or greater than the height of its bounding box, or in case of a computed overflow-y of clip, its content box.
Note: A viewport size of 640 by 512 is equivalent to a viewport size of 1280 by 1024 zoomed 200%.
