How to modify font style in javascript

JavaScript is a widely used programming language that can add many interesting features to web pages. One of the interesting features is modifying font styles. In this article, we will show you how to modify font styles using JavaScript.

First, let’s take a look at how to modify the font style through CSS. Usually, we can set the font, size, color and other styles for the text in the web page. For example, to set the font style of a paragraph to Helvetica, we can use the following code:

p {
   font-family: Helvetica;
}

But sometimes we need to dynamically modify the font style according to the user's needs. At this time we can use JavaScript to achieve this. Here are a few examples of modifying font styles.

document.getElementById("myText").style.fontSize = "24px";

The above code will set the font size of the element with the ID "myText" is 24 pixels. You can replace "myText" with your desired ID name and "24px" with your desired font size.

Modify the font style

To modify the font style, we can use the following code:

document.getElementById("myText").style.fontStyle = "italic";

The above code will set the font style of the element with the ID "myText" in italics. You can replace "myText" with your desired ID name and "italic" with your desired font style name.
