Fixed position but relative to container

Fixed Position but Relative to Container: A Guide

Do you ever feel like you're swimming against the current when it comes to web development? 🏊‍♂️ You have a div that needs to stay fixed at the top of the screen, but it's inside a centered container. 😫 You try using position: fixed, but it stubbornly stays glued to the right side of the browser, rather than the container. What's a developer to do? 🤔

The Problem

The issue here is that position: fixed positions an element relative to the browser window 🖥️, not its container. So, when you scroll down the page, the element stays fixed, but it doesn't stick to the top as desired.

A Hacky Solution

One possible workaround to achieve the desired effect is to use position: sticky instead of position: fixed.

.container {
  position: relative;
  width: 60%; /* Adjust this to match your container width */
  margin: 0 auto; /* Center the container */
}

.sticky-div {
  position: sticky;
  top: 0;
}

Here's what's happening:

1. We give the container a position: relative so that its children can be positioned relative to it.

2. We add the width and margin: 0 auto properties to center the container on the page. Adjust the width to match your container's width.

3. We set the position property of the div you want to fix to sticky and give it a top value of 0px to ensure it sticks to the top of the container.

Example usage

<div class="container">
  <!-- Your content here -->
  <div class="sticky-div">
    I'm a sticky div! 📌
  </div>
</div>

Other Considerations

Keep in mind that the sticky position value is not supported in older browsers like Internet Explorer. So, if your target audience includes those users, you may need to find an alternative solution.

Conclusion

You've just learned how to achieve a fixed position relative to a container! 🎉 By using position: sticky along with a container that has a position: relative, you can now stick elements to the top of the container and enjoy a smoother scrolling experience. No more stubborn divs glued to the browser window! 🙌
