A style attribute on a <dt> tag assigns a unique style to the element.
Its value is CSS that defines the appearance of the dt element.
A style attribute on a <dt> tag.
<dl>
<dt style="background-color:cornsilk;">Kunstmuseum</dt>
<dd>Basel, Switzerland</dd>
<dt style="background-color:cornsilk;">National Gallery of Art</dt>
<dd>Washington DC, USA</dd>
<dt style="background-color:cornsilk;">Musée d'Orsay</dt>
<dd>Paris, France</dd>
</dl>
The style attribute specifies the style, i.e. look and feel, of the <dt> 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 <dt> element only.
<dt style="CSS-styles" >
| Value | Description |
|---|---|
| CSS-styles | One or more CSS property/value pairs separated by semicolons (;). |
A style attribute on a <dt> tag.
Clicking the button toggles the background color.
<dl id="mydl">
<dt style="background-color:cornsilk;">Kunstmuseum</dt>
<dd>Basel, Switzerland</dd>
<dt style="background-color:cornsilk;">National Gallery of Art</dt>
<dd>Washington DC, USA</dd>
<dt style="background-color:cornsilk;">Musée d'Orsay</dt>
<dd>Paris, France</dd>
</dl>
<br/>
<button onclick="toggle();">Toggle style</button>
<script>
let toggle = () => {
let elements = document.getElementById("mydl").getElementsByTagName("dt");
[].forEach.call(elements, element => {
if (element.style.backgroundColor === "cornsilk") {
element.style.backgroundColor = "moccasin";
} else {
element.style.backgroundColor = "cornsilk";
}
});
}
</script>
The style attributes assign a background color to all <dt> elements.
Clicking the button locates all <dt> elements.
It then iterates over the elements and toggles another background color.
