HTML <button> style Attribute

HTML <br>

HTML <canvas>

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

Its value is CSS that defines the appearance of the button.

Example

#

A style attribute on a <button> tag.

<button style="background:#3630a3;color:white;"
        onclick="alert('Save processed.')">
        Save</button>

<button style="background:#3630a3;color:white;"
        onclick="alert('Action cancelled.')">
        Cancel</button>

Using style

#

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

Syntax

#

<button style="CSS-styles" >

Values

#

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

More Examples

#

A style attribute on a <button> tag.
Clicking the second button toggles the background color.

<button type="button" id="mybutton" 
        style="background: darkcyan;color:white;"
        onclick="alert('Filter was clicked!');">Filter</button>

<br />
<button type="button" onclick="toggle();">Toggle style</button>

<script>
  let toggle = () => {
    let element = document.getElementById("mybutton");

    if (element.style.backgroundColor === "darkcyan") {
       element.style.backgroundColor = "#3630a3";
    } else {
       element.style.backgroundColor = "darkcyan";
    }
  }
</script>

Code explanation

The style attribute assigns a background color to the <button> element.

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