Understanding Sticky Positioning in Web Design

When designing a webpage, it’s common to desire elements that hold their position as you scroll. One such feature is the sticky positioning of div elements. This might seem confusing, particularly when you want certain elements to be positioned under others while still remaining functional during scrolling. In this guide, we will address a specific question: how to make a div scroll to stick inside another div and under a fixed header.

The Challenge

Imagine you have a card (or section) on your webpage, and within that card, you want to have a header that remains fixed at the top, while one or more elements scroll beneath it. The two main objectives are:

Making the h2 header fixed, but not to the top of the page.

Achieving the sticky behavior for other div elements that stay under the header without scrolling the entire page.

Here’s an initial HTML structure representing this:

Final Touch: Managing Element Visibility

To achieve the effect where one div fully appears when scrolled to the designated point (without gradual animation or cropping), consider implementing transitions or JavaScript for more complex interactions, which is beyond static CSS but can enhance user experience effectively.

Conclusion

Achieving a sticky div under a fixed header requires correct positioning and proper CSS styling. By following the steps outlined above, you can ensure that your elements behave as intended while creating a smooth user experience on your webpage.
