How to Change the CSS Style of a Class in JavaScript?

Changing the CSS Style of a Class in JavaScript

In web development, it's common to manipulate elements to change their appearance or behavior. One frequent action is to toggle the display of an element, which can be controlled through CSS.

If you have a class with the display property set to none, and you want to change it to inline using JavaScript, there is a potential concern. While you can directly use getElementById to modify the style of an element by ID, the approach for classes is slightly different.

Solution

The suggested solution involves utilizing the styleSheets array, a browser-provided JavaScript API. It allows you to access and modify the CSS styles applied to your page. Using this array, you can change the CSS rules associated with specific classes.

Alternative Recommendation

While you can use the styleSheets array to modify class styles, it's generally recommended to avoid making such direct changes. A cleaner and more maintainable approach is to define a separate CSS style that includes the display: none property. When you want to display the element, you can add this style to the element using JavaScript.

By following this alternative recommendation, you maintain a cleaner separation of concerns between your JavaScript and CSS code, making it easier to manage and avoid potential conflicts.
