Is it possible to alter CSS based on the width of the webpage using javascript

We are currently developing a web application that will be deployed on various devices such as mobile phones, iPads, iPhones, and Android. Instead of using user agents to show different views, I prefer having CSS that adjusts based on the screen width.

We have utilized jQuery to modify the CSS for one section so that it takes up less vertical space when the width is reduced (as shown below).

How can I implement this for buttons in a way that allows them to stack horizontally if the screen width is narrow enough to prevent all buttons from fitting in a single row? Once that's achieved, I can focus on refining the button appearance.

Answer №1

To alter the CSS based on page width, you can utilize Media Queries which do not necessitate JavaScript.

For an insightful introduction to Responsive Web Design by the pioneer of the concept, check out: http://www.alistapart.com/articles/responsive-web-design/

If modifying page content according to page width is your aim, a tool like RESS could be beneficial. A simple script for this purpose can be found here, though it relies on cookies and doesn't adjust upon screen resize. In general, unless necessary, media queries are recommended over this method.
