A style attribute on an <option> tag assigns a unique style to the option.
Its value is CSS that defines the appearance of the option.
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>
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.
<option style="CSS-styles">
Value | Description |
---|---|
CSS-styles | One or more CSS property/value pairs separated by semicolons (;). |
A style attribute on <option> elements.
Clicking the button toggles the thickness of the option text.
<select id="myselect">
<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;"style="background: #dfe7ff;color:#4e46e5;">India</option>
</select>
<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>
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.
