If the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text. (Level AA)

Rationale

When technology is capable of achieving a desired visual presentation, developers must use text -- not images of text -- to allow people with disabilities to adjust the text presentation per their personal preferences. For example, a user may require a particular text size, font family or text/background color.

The definition of image of text contains the note: "This does not include text that is part of a picture that contains significant other visual content." Examples of such pictures include graphs, screenshots, and diagrams that visually convey important information beyond text only.

Customizable Exception: This checkpoint does not apply to images of text that can be visually customized to the user's requirements.

Essential Exception: This checkpoint does not apply when a particular presentation of text is essential to the information being conveyed. For example, logotypes (text that is part of a logo or brand name) are considered essential.

Development Techniques

Review the General techniques as well as other tabs applicable to your technology.  Prioritize the use of technology-specific techniques, and implement the General techniques as needed. You are always required to find, understand and implement accessible code techniques to meet the checkpoint. The documented techniques and supplements are not exhaustive; they illustrate acceptable ways to achieve the spirit of the checkpoint. If numbered, techniques are in order of preference, with recommended techniques listed first. Where used, IBM information that complements the WCAG techniques is indicated as supplemental.

General techniques

Any item in this section represents a technique deemed sufficient.

Web (HTML, ARIA, CSS) techniques

In addition to the General techniques, the Web (HTML, ARIA, CSS) techniques in this section represent a technique or combination of techniques that is deemed sufficient for meeting this checkpoint.

Present information as text rather than using an image by implementing the following techniques:

Mobile Native (iOS) techniques

There are no specific iOS techniques for this checkpoint. Refer to the General techniques section.

Eclipse techniques

Instructions: Except for the cases outlined in this checkpoint (1.4.5) for customizable and essential images of text, Eclipse applications must use the following techniques. Using these techniques is sufficient for meeting the requirements of this checkpoint (1.4.5).

Windows-based (MSAA+IA2) techniques

Instructions: Except for the cases outlined in this checkpoint (1.4.5) for customizable and essential images of text, Windows-based (MSAA+IA2) applications must use the following techniques. Using these techniques is sufficient for meeting the requirements of this checkpoint (1.4.5).
