Style Position Fixed in a better way

.fixed {
  position: fixed;
  left: 0;
  right: 0;
  background: #000;
  bottom: 0;
  z-index: 100;
}

 class="parent">
     class="fixed-child-content">
         class="inner">
            This is position fixed content.
        

.parent {
  max-width: 768px;
  width: 100%;
  ...
}

.fixed-child-content {
  position: fixed;
  bottom: 0;
  max-width: inherit;
  width: 100%;
  ...
}

In the provided code, we have defined a parent container with the class name “parent”. The maximum width of this container has been set to 768 pixels, while its width has been set to 100%, allowing it to take up the entire available width.

For the child element with the class name “fixed-child-content”, we have set the position to “fixed”. This means that the element will be removed from the normal document flow and remain fixed within the viewport.

The key aspect of this code is setting the maximum width to “inherit” for the child element. This ensures that it will inherit the maximum width specified by its parent element, in this case, the “parent” class. Additionally, we have set the width to 100%, allowing the fixed element to take up the entire width of its container.

Overall, this approach allows the fixed content to match the maximum width of its parent container, providing flexibility in controlling the position of the fixed content.

Please note that the fixed content should be a direct child of its parent section.

Difficulties and Challenges

In addition, there are several challenges and issues that can arise when using position: fixed.

Overlapping Content

One of the primary concerns with fixed positioning is the potential for overlapping content. If fixed elements are not positioned with consideration for the surrounding content, they can obstruct important information or render parts of the page inaccessible.

Responsive Design Limitations

Fixed elements may not behave as expected on smaller screens, leading to inconsistencies in visual design or functionality.

Scrollable Areas

Using position: fixed within scrollable areas, such as divs with overflow properties, can result in conflicts. The fixed element may not scroll with the rest of the content within the scrollable area, leading to a disjointed user experience.

Performance Impact

Rendering fixed elements can impact page performance, particularly on lower-end devices or when working with complex layouts. Browsers need to continuously re-render fixed elements as users scroll, which can reduce performance and increase CPU usage.

Limited Placement Flexibility

While position: fixed allows for precise element placement, it can also limit positioning flexibility. Fixed elements are restricted to the viewport and cannot be positioned outside of it. This limitation can restrict creative possibilities for design concepts or interactions that require elements to be positioned in non-standard locations.
