HTML <textarea> style Attribute

The style attribute on a <textarea> tag assigns a unique style to the multi-line textarea. A style contains one or more CSS property/value pairs that define the appearance of the textarea element.

Example

#

A style attribute on a <textarea> element.

<textarea placeholder="Enter your opinion here ..."
          style="width: 350px;height: 200px;
                 padding: 10px; border:3px dashed indigo;
                 background-color:aliceblue;">
</textarea>

Using style

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

     let element = document.getElementById("mytextarea");

     if (element.style.backgroundColor === "aliceblue") {
       element.style.backgroundColor = "seashell";
       element.style.borderColor = "chocolate";
    } else {
       element.style.backgroundColor = "aliceblue";
       element.style.borderColor = "indigo";

The style attribute assigns a background and border colors to the <textarea> element.

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