change size text in javascript

To change the size of text using JavaScript, you can use the style property of the element and set the fontSize property to the desired text size. Here's an example:

index.tsx
// Get the element
let textElement = document.getElementById("myText");

// Set the font size
textElement.style.fontSize = "20px";
131 chars
6 lines

In the above code snippet, we first get the element with the ID of "myText". Then, we set the fontSize property of the style property to "20px". This will change the font size of the text to 20 pixels.

Alternatively, you can also use CSS to change the size of text. Here's an example:

/* CSS */
#myText {
  font-size: 20px;
}
41 chars
5 lines

In this example, we use CSS to set the font size of the text. We target the element with the ID of "myText" using the # selector and set the font-size property to 20 pixels.
