iframe Height 100% Not Working? Here’s How to Fit the Entire Screen Height

In many web projects, you might face a common issue where an iframe doesn’t fill the entire screen height as expected, leading to unwanted scrolling. Luckily, there are several strategies to address this problem effectively using JavaScript, jQuery, and HTML.

Why iframe Height 100% Doesn't Work

Several factors can contribute to the failure of an iframe to render at 100% height. The parent container might not have a defined height or the height is influenced by other elements around it. This results in the iframe not expanding to full height by default.

Solution Using CSS and HTML

Ensure that both the iframe and its parent elements have their heights set correctly in CSS. Here's a step-by-step method:

Set HTML and Body height to 100%:

By setting the html, body, and the container .iframe-container to 100% height, the iframe will extend to fill the entire screen.

Adjusting iframe Height with JavaScript/jQuery

In some cases, you might need a dynamic adjustment beyond static CSS. JavaScript or jQuery can be highly useful:

These scripts will dynamically adjust the height of the iframe to match the browser window height whenever the window is loaded or resized.

Whether you choose to use CSS for a fixed solution or JavaScript/jQuery for a dynamic approach, ensuring your iframe fits the entire screen height without extra scrolling is absolutely achievable. Follow the steps outlined above to integrate a perfectly-sized iframe into your web project.
