change javascript font

JavaScript is a very useful programming language that can make web pages more lively and interesting. In web development, it is often necessary to change fonts to beautify the page, and this operation can be easily achieved using JavaScript.

In this article, we’ll cover how to use JavaScript to change font size, font type, and other style properties.

1. Change the font size

To change the font size, we can use JavaScript to modify the fontSize attribute in the element's style attribute. The code is as follows:

document.getElementById("myElement").style.fontSize = "20px";

This will change the font size of the element with id "myelement" to 20 pixels. We can also use other units like em, pt or %.

2. Change the font type

To change the font type, we need to use the fontFamily attribute. The code is as follows:

document.getElementById("myElement").style.fontFamily = "Arial";

This will change the font type of the element to Arial. You can also use other commonly used fonts, such as Helvetica, Times New Roman, and Verdana.

3. Change the font color

To change the font color to another color, we can use the color attribute. The code is as follows:

document.getElementById("myElement").style.color = "red";

This will change the font color of the element to red. You can also use other colors such as blue, green or #FF00FF etc.

4. Change other style attributes

In addition to the above basic style attributes, you can also use other style attributes to change the appearance of the element. Some of the available properties include:

• fontWeight: The weight of the text can be changed to normal or bold.
• textDecoration: You can add underline or strikethrough effects.
• fontStyle: Text can be set to italic.
• textTransform: Text can be changed to uppercase or lowercase.

Code sample:

document.getElementById("myElement").style.fontWeight = "bold";
document.getElementById("myElement").style.textDecoration = "underline";
document.getElementById("myElement").style.fontStyle = "italic";
document.getElementById("myElement").style.textTransform = "uppercase";
