HTML <i> class Attribute

HTML <html>

HTML <iframe>

The class attribute assigns one or more CSS class names to the <i> tag.

Class names are defined in a stylesheet or in a local <style> element.

Classes, i.e. class names, are used to style elements.

Example

Van Gogh and Gauguin visited Montpellier in December 1888.

<style>
  .i-underline { text-decoration: underline; }
</style>

<article>
  <p>
    Van Gogh and Gauguin visited 
    <i class="i-underline">Montpellier</i> in December 1888.
  </p>
</article>

More Examples

#

A class attribute styling an <i> element.
Clicking the button toggles a classname that changes the background color.

Van Gogh and Gauguin visited Montpellier in December 1888.

<style>
  .i-underline { text-decoration: underline; }
  .lavender-bg { background-color:lavender; }
</style>

<article>
  <p>
    Van Gogh and Gauguin visited 
    <i id="myi" class="i-underline">Montpellier</i> 
    in December 1888.
  </p>
</article>

<br/>
<button onclick="toggle();">Toggle class</button>

<script>
  let toggle = () => {
    let element = document.getElementById("myi");
    element.classList.toggle("lavender-bg");
  }
</script>

Code explanation

Three CSS classes are defined in the <style> element.

The class attribute in <i> assigns the two of those.

Repeatedly clicking the button toggles another class, changing the <i> underline.
