![]() ![]() ![]() ![]() MathML is therefore able to provide sufficient information and structure of the math to support both visual display and assistive technology access. MathML is composed of a number of Extensible Markup Language (XML) tags that provide the means to mark up an equation in terms of both presentation and semantics, thus enabling the expression of the information content or meaning behind equations and not just the visual representation. Although alternate text descriptions (commonly in the form of "alt tags") can be added to these images, this approach has drawbacks because text does not always provide true comparable access to information found in mathematical notation. Such a practice is problematic because graphical images are inherently inaccessible. Using MathML provides the highest level of accessibility to math within digital documents.īefore the advent of MathML, web authors often resorted to inserting graphical images, basically digital "pictures" of equations taken from other software products, into their documents. MathML is needed because HTML has no means of marking up mathematical expressions. ![]() Like the more familiar HyperText Markup Language (HTML), which sets the standard for web browsers to display literary text, MathML is an international open standard for encoding math content. MathML (Mathematical Markup Language) is an industry standard adopted by the World Wide Web Consortium (W3C) as the approved way of expressing math on the web. ![]()
