checking if the height of the body is less than 100% using javascript or jquery

On my website, I didn't set a height for the html or body tags. This setup works well on pages with ample content, but when a page has insufficient content, I want the body height to be 100%.

I decided to try using jQuery to solve this issue. I came up with a snippet that I thought would work, but unfortunately it didn't do much.

if(jQuery("html").css("height") < "100%"){
    jQuery("html, body").css({"height": "100%", "min-height":"100%"});
}

I suspect that jQuery may not be recognizing the body height as a percentage, perhaps only in pixels.

Your assistance would be greatly appreciated.

Answer №1

To achieve a 100% height layout, you can do so without the need for any javascript.

Take a look at these resources:

(I have personally used this in my projects)

If you prefer to use jQuery for this purpose, you can utilize the following code snippets:

$(window).height();   // returns height of browser viewport
$(document).height(); // returns height of HTML document

You can determine if the document height is less than the window height by comparing the two, and adjust the document or container accordingly.

Answer №2

To style your webpage, add the following CSS rules to target the body and html elements:

html, body { min-height:100%; height:auto }
