How to Prevent Animated Elements from Expanding Your Web Page

When adding eye-catching animations to web pages, one common issue developers encounter is that these animated elements can cause the page to expand beyond its intended dimensions. If you’ve ever faced the frustration of an animated element disrupting your layout, you’re not alone. In this guide, we’ll explore how to effectively manage animated elements so that they don’t affect the overall sizing of your web page.

Understanding the Issue

The main challenge arises when animations, particularly scaling animations, increase the size of an element to the point where it overflows its container. The result is an undesirable alteration to your page’s structure and dimensions. This can lead to awkward scroll bars, unintended white space, or elements that move out of place.

In our scenario, we have a ripple-background with various circles that animate using CSS, but the animation causes it to expand beyond its boundaries.

Initial Example

Here’s a simplified version of the original HTML and CSS:

The Solution

To correct this issue, we need to encapsulate the animated element within a parent container that effectively controls its overflow. This is where CSS properties like overflow: hidden; come into play.

Step-by-step Implementation

Create a Parent Wrapper:
Begin by wrapping your ripple-background in a div that will serve as the container. This wrapper will dictate the dimensions and overflow behavior of the animated contained elements.

Set Overflow Properties:
Apply overflow: hidden; to the parent wrapper to ensure that any part of the animated content which scales out of bounds is hidden from view.

Define Wrapper Dimensions:
Make sure the wrapper covers the entirety of the viewport to contain the animation properly.

Here’s how you can implement it:

Conclusion

By carefully using a parent container along with the overflow property, you can contain the effects of animated elements and prevent them from unnecessarily expanding the page size. This technique not only keeps your layout intact but also enhances the user experience by eliminating unwanted scroll bars and ensuring a polished appearance.

Get Started

Try implementing this method in your own projects. By following these steps, you’ll be able to have smooth animations without compromising your web page's structure!
