HTML <object> style Attribute

The style attribute on a <object> tag assigns a unique style to the embedded object. A style contains one or more CSS property/value pairs that define the appearance of the object element.

Example

#

A style attribute on an embedded <object> element.

PDF cannot be displayed.
<object style="border:25px solid paleturquoise;padding:10px;
               width:100%;height:500px;padding:4px;"
        data="/media/sample.pdf" type="application/pdf">
   PDF cannot be displayed.
</object>

Using style

The style attribute specifies the style, i.e. look and feel, of the <object> element.

A style contains any number of CSS property/value pairs, separated by semicolons (;).

The style attribute overrides any other style that was defined in a <style> tag or an external CSS file.

This inline styling affects the current <object> element only.


Syntax

<object style="CSS-styles">

       element.style.borderColor = "mediumturquoise";
    } else {
       element.style.borderColor = "paleturquoise";
    }
  }
</script>

Code explanation

The style attribute assigns a border color to the <object> element.

Clicking the button calls JavaScript which toggles the border color to another color.
