"mrow" as Virtical Stretch Boundary
Q
How virtical stretch is applied within a <mrow> element?
✍: FYIcenter.com
A
<mrow> element is the default boundary
for vertically stretched operators.
The example below shows that parentheses on the left side are not stretched because of the <mrow> boundary.
<math><mi>f</mi><mo></mo>
<mrow><mo>(</mo><mi>x</mi><mo>)</mo></mrow><mo>=</mo>
<mo>(</mo><mfrac><mfrac><mn>1</mn><mn>2</mn></mfrac>
<mn>3</mn></mfrac><mo>)</mo></math>
The example below shows that parentheses on both sides are stretched without the <mrow> boundary.
<math><mi>f</mi><mo></mo>
<mo>(</mo><mi>x</mi><mo>)</mo><mo>=</mo>
<mo>(</mo><mfrac><mfrac><mn>1</mn><mn>2</mn></mfrac>
<mn>3</mn></mfrac><mo>)</mo></math>
Note that some old browsers do not support automatical stretched operators. In this case, you can try the <mfenced> element to replace stretched operators:
⇒ Horizontally Stretched Operators
⇐ Vertically Stretched (Fence) Operators
