HTML <details> style Attribute

HTML <del>

HTML <div>

A style attribute on a <details> tag assigns a unique style to the element.

Its value is CSS that defines the appearance of the details element.

Example

<details style="background-color:aliceblue;padding:10px;">
  <summary>Van Gogh's Paintings</summary>

  <p>Self Portrait</p>
</details>

Using style

#

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

Syntax

#

<details style="CSS-styles" >

Values

#

Value	Description
CSS-styles	One or more CSS property/value pairs separated by semicolons (;).

Clicking the button calls JavaScript which changes the background color.
