Check whether all content scales and is perceivable with no loss of content or functionality (e.g.Increase zoom (for all content) to 400%.Display content in a user agent with a window width of 1280px.Question from Alastair: Do you ever get issues decreasing the size? I can't think of an example where you would, so do we need to include that as a requirement? Users can see and interact with all content and user interface controls presented visually, including when users have changed display settings such as text size, magnification, and cursor appearance. Source: Accessibility Requirements for People with Low Vision, Section 3.7.1 Some users increase the size of mouse pointers in their operating system or with screen magnification software. Scrollbars generally provide the additional benefit of communicating where the user is in an interface. In such cases, it is usually best practice for scrollbars to be provided for the dialog box. When people use large fonts or lower screen resolution, it is not uncommon for dialog boxes to include information that is not in the viewport. See also the Rewrap for one direction scrolling section. When the areas cannot be resized to accommodate all content, usually a scrollbar should be available. Often it is best for text areas to automatically resize to fit the text, and for users to be able to change the size of text areas. If the user needs to increase content more than 400%, then reflow would be necessary which overrides the layout of the website. The size 400% was picked as the largest size a standard website can get to using responsive design. Simply put: a person can make everything bigger or smaller as needed. Zoom functions preserve all spatial relationships on the page and all functionality continues to be available. Principle 1, Guideline 1.4.4 Resize text Description What Principle and Guideline the SC falls within.
