height Attribute | height Property

Sets or retrieves the height of the object .

When you use the !DOCTYPE declaration to specify standards-compliant mode, this property specifies only the distance between the top and bottom edges of the content box—that is, within the padding .

Syntax

HTML Scripting

{ height : sHeight }

object . style.height [ = sHeight ]

Possible Values

sHeight

Variant that specifies or receives one of the following values.

auto	Default.
height	Floating-point number followed by an absolute units designator ( cm , mm , in , pt , pc , or px ) or a relative units designator ( em or ex ). For more information about the supported length units, see CSS Length Units Reference .
percentage	Integer followed by a percent sign (%). The value is a percentage of the height of the parent object, which must be specified explicitly. Negative values are not allowed.

The property is read/write for all objects except the following, for which it is read-only: currentStyle . The property has a default value of auto . The Cascading Style Sheets (CSS) attribute is not inherited.

Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties .

Remarks

If you specify the height property of an img object but not the width property, the width is proportional to the height according to the dimensions of the image source file.

As of Internet Explorer 6, when you use the !DOCTYPE declaration to specify standards-compliant mode, this property specifies the distance between the top and bottom edges of the content box—that is, within the padding .

When the !DOCTYPE declaration does not specify standards-compliant mode, and with earler versions of Internet Explorer, this property includes the object's content box, plus the values of the following properties: borderTop , borderBottom , paddingTop , and paddingBottom . Subtracting the sum of the values of these properties from the value of the height property equals the height of the parent object's content box.

To perform operations on the numeric value of this property, use pixelHeight or posHeight .

Examples

This example uses an inline style sheet to set the height of an image to 4 centimeters.

<IMG SRC="sphere.jpg" STYLE=" height :4cm"> Show Me

This example uses inline scripting to change the height of an image when an onclick event occurs.

<BUTTON onclick="height1.style. height ='1cm'">Shrink sphere</BUTTON>
