Customizing CSS for Various Browser Sizes

I have a query regarding window-dependent CSS. It seems to be a common issue, but I am facing some difficulties with it on Wordpress. I am currently using the script recommended by Nettuts. My goal is to apply different CSS styles based on the user's window size. To achieve this, I know that I need to utilize $(window).width(). Here is what I have implemented so far:

function checkWindowSize() {

    if ( $(window).width() < 800 ) {
        $('body').addClass('small');
    }
    else {
        $('body').removeClass('small');
    }

}

$(window).resize(checkWindowSize);

This code works as intended. However, there is a minor issue. When I resize the window to below 800px and then refresh the page with F5, the new CSS style is not applied until I manually resize the window by even just 1px. It does not automatically update when the window is smaller than 800px upon refreshing. I have attempted adjusting the order of the scripts, such as placing the new CSS before the existing CSS, but it did not resolve the problem.

Any suggestions or insights on how to address this issue would be greatly appreciated. If my explanation is unclear, please let me know :)

Answer №2

If you want to dynamically load different CSS files based on screen width, consider using a tool like Adapt.js. Adapt.js detects the screen width and switches the appropriate CSS file either when the window is resized or when the tablet or phone is tilted.

Alternatively, for older browser support, you can utilize Media Queries along with a polyfill, instead of relying on Adapt.js.

Answer №3

Make sure to trigger it when the window is first loaded:

function adjustWindowSize() {

    if ( $(window).width() < 800 ) {
        $('body').addClass('small');
    }
    else {
        $('body').removeClass('small');
    }

}
$(window).load(adjustWindowSize);
$(window).resize(adjustWindowSize);

Answer №4

Make sure your checkWindowSize method is being triggered not only upon window resizing, but also when the page is initially loaded. If you only have it set to execute on resize events, then it won't run when the page is first loaded and the size won't be checked or the class won't be added.

To fix this issue, add this line of code in addition to what you already have:

$(function() { checkWindowSize(); });

Answer №5

Using media queries is the recommended approach for responsive design. You may have come across HTML code similar to this:

<link href='style.css' type='text/css' rel='stylesheet' media='screen'>

The W3C has implemented Mediaqueries as a way to specify the appropriate media for stylesheets, eliminating the need for browser detection and allowing functionality without relying on javascript.
