Using style

#

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

Syntax

#

<thead style="CSS-styles">

<script>
  let toggle = () => {
     let element = document.getElementById("mythead");

     if (element.style.backgroundColor === "navy") {
       element.style.backgroundColor = "royalblue";
    } else {
       element.style.backgroundColor = "navy";
    }
  }
</script>

Code explanation

The style attribute assigns a background color to the <thead> element.

Clicking the button calls JavaScript which toggles the background to another color.
