    Todo: Live demos.

    Notes:

    • In general you can get additional stylistic effects by using CSS rules in the <style>...</style> element in the standard CSS way.
    • You can also use the <script>...</script> element in the usual (X)HTML way to perform dynamic operations in the document, including the math content (see for example the interactive sizing in the demo of mspace).

     

    Working demos so far:
    mfrac, mo, mtable, mspace, mmultiscripts, msqrt-mroot

    Top-level Element


    <math   -- top-level element
    >>Demo... 
     %att-common

    Compatibility: MathML 1.x, MathML 2.0
    Status: Implemented by building upon the CSS block and inline box model code. As a benefit of this, linebreaking is supported between children of the <math> element.
    Issues: Some limitations exist due to the specifities of MathML. To prevent expressions from breaking in a non-math aware manner and to ensure that the stretching of stretchy operators is performed adequately, you may need to wisely group related children using <mrow>.

    Compatibility: MathML 2.0
    Status: Not yet implemented in Mozilla.
    Issues: Can have portability problems because certain fonts may not necessarily be identical across platforms and encoding types (e.g., TrueType vs. Type 1).

    Status: Implemented by leveraging on the CSS2 table model code
    Issues:
    • Some limitations exist due to the specifities of MathML
    • The interpretation of rowspan and columnspan is meant to correspond with the similar attributes for HTML 4.01 tables. In particular columnspan="0" (resp. rowspan="0") means that that the cell spans all columns (resp. rows) from the current column (resp. row) to the last column (resp. row) of the table.

    Issues:  
    Tips: You can achieve more powerful dynamic effects in Mozilla by instead using the combined breadth and depth of JavaScript and the Document Object Model down to any individual MathML tag as demonstrated on this JavaScripted MathML editor.

    Extras (technology demonstration, non-portable)


    >>Demo...

    • title attribute as a tooltip (from XHTML)
    • mixing MathML with other markups, e.g., <img>, <form>
    • and more.
