HTML <strong> style Attribute

HTML <span>

HTML <style>

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

Its value is CSS that defines the appearance of the strong element.

Example

#

A style attribute on a <strong> tag.

Homework is due on March 11.

<p>
  Homework is due on <strong style="color: teal;">March 11</strong>.
</p>

Using style

#

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

Syntax

#

<strong style="CSS-styles">

Values

#

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

<p>

  <strong id="mystrong" style="color: teal;">March 11</strong>.
</p>

<br />
<button onclick="toggle();">Toggle style</button>

<script>
  let toggle = () => {
     let element = document.getElementById("mystrong");

     if (element.style.color === "teal") {
       element.style.color = "tomato";
    } else {
       element.style.color = "teal";
    }
  }
</script>

Code explanation

The style attribute assigns a text color to the <strong> element.

Clicking the button calls JavaScript which toggles the text color to a different one.
