border-top-style Attribute | borderTopStyle Property

Sets or retrieves the style of the top border of the object.

Syntax

HTML { border-top-style: sStyle }

Scripting object.style.borderTopStyle [ = sStyle ]

HTML	{ border-top-style: sStyle }
Scripting	object.style.borderTopStyle [ = sStyle ]

Possible Values

sStyle String that specifies one of the following values:

none No border is drawn, regardless of any specified border-width.

dotted Border is a dotted line on the Macintosh platform as of Internet Explorer 4.01, and a solid line on the Windows and Unix platforms.

dashed Border is a dashed line on the Macintosh platform as of Internet Explorer 4.01, and a solid line on the Windows and Unix platforms.

solid Border is a solid line.

double Border is a double line drawn on top of the background of the object. The sum of the two single lines and the space between equals the border-width value. The border width must be at least 3 pixels wide to draw a double border.

groove 3-D groove is drawn in colors based on the value.

ridge 3-D ridge is drawn in colors based on the value.

inset 3-D inset is drawn in colors based on the value.

outset 3-D outset is drawn in colors based on the value.

The property is read/write with a default value of none; 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 dynamic properties.

Remarks

To use this property, inline elements must have an absolute position or layout. Element layout is set by providing a value for the height property or the width property.

A border-width greater than 0 must be set for the border-top-style attribute to render.

Example

The following examples use the border-top-style attribute and the borderTopStyle property to specify the style of the top border.
This example uses a call to an embedded (global) style sheet to change the style of the top border from solid to groove when an onmouseover event occurs.
Sample Code
<HEAD>
<STYLE>
    TD { border-top-style:solid;
        border-width=0.3cm }
    .change { border-top-style:groove}
</STYLE>
</HEAD>
<BODY>
<TABLE BORDER>
<TR>
    <TD onmouseover="this.className='change'" 
        onmouseout="this.className=''">
        <IMG src="sphere.jpg">
    </TD>
</TR>
</TABLE>
