HTML <option> style Attribute

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

Example

#

A style attribute on four <option> elements.

<select>
  <option>-- Select country --</option>
  <option style="background: #dfe7ff;color:#4e46e5;">United States</option>
  <option style="background: #dfe7ff;color:#4e46e5;">United Kingdom</option>
  <option style="background: #dfe7ff;color:#4e46e5;">Thailand</option>
  <option style="background: #dfe7ff;color:#4e46e5;">India</option>
</select>

Using style

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

<br />
<button onclick="toggle();">Toggle class</button>

<script>
  let toggle = () => {
    let elements = document.getElementById("myselect").getElementsByTagName("option");
    [].forEach.call(elements, element => {
        if (element.style.fontWeight === "700") {
          element.style.fontWeight = "400";
        } else {
          element.style.fontWeight = "700";
        }
    });
  }
</script>

Code explanation

The style attribute assigns a font weight to the <option> elements.

Clicking the button calls JavaScript which locates all the <option> elements.

It then iterates over the elements and toggles the text boldness.
