Why Doesn\'t My JavaScript Code Change Font Size?

Font Size Adjustment in JavaScript

JavaScript offers versatile functionality for manipulating page elements, including the ability to adjust font sizes. However, when attempting to make such changes, it's crucial to consider the case sensitivity of JavaScript.

The code snippet provided in the query, aimed at modifying the font size of an HTML element, fails to produce the desired effect due to a common pitfall in JavaScript. The property used to specify font size is "fontSize," where each character's case Matters. In the erroneous code, "fontsize" is used instead, resulting in no visible change.

To rectify this issue and successfully adjust the font size using JavaScript, the correct syntax is:

span.style.fontSize = "25px";

This alteration ensures that the case-sensitive property is used, leading to the desired change in font size. By adhering to the proper case, developers can effectively manipulate page elements and achieve their desired styling outcomes.
