In modern web development, creating scrolling effects has become a common practice to enhance user experience. Smooth scrolling to a specific element is often accompanied by a fixed header that remains visible while scrolling through content. This combination creates a seamless user experience, allowing users to navigate through sections effortlessly.
But there are often issues with fixed or sticky headers while scrolling to an element. The header can block the element from view. This can be frustrating for users, as they may have to scroll past the header to see the element they’re interested in.
In this blog post,
we will explore how to implement smooth scrolling
scrollIntoView in a React application while incorporating a fixed header.
Before diving into the example,
let’s understand about native
scrollIntoView method is used to scroll an element
into the visible area of the browser window.
scrollIntoView(alignToTop, scrollIntoViewOptions) alignToTop(optional) true: The top of the element will be aligned to the top of the visible area of the scrollable ancestor. The default is true. false: The bottom of the element will be aligned to the bottom of the visible area of the scrollable ancestor. scrollIntoViewOptions(optional) An Object with the following properties: behavior: Determines scroll animation - smooth: Smooth scrolling - instant: Instant scrolling in a single jump - auto: Scroll behavior is determined by the computed value of scroll-behavior block: Defines vertical alignment (start, center, nearest) inline: Defines horizontal alignment. (start, center, nearest) Return value: None(undefined)
During one of our client projects, we encountered a specific need to implement scrolling to a particular element. The scenario involved a list of upcoming meetings, some of which may have already ended. Our objective was to ensure that the user always sees the next upcoming meeting on the list, without modifying the existing logic.
To fulfill this requirement, we incorporated a feature that enables scrolling directly to the subsequent upcoming meeting.
In the following sections, we will delve into the implementation details of this functionality.
We used Material UI as a component library for our project.
constant.js, we defined the data, and in
we loop over the sub-headers to get the meeting list.
Note, the sub-headers are fixed.
We make use of a
useRef to store a reference to the element
that we want to scroll to i.e. the next upcoming meeting.
We wanted to scroll to the next upcoming meeting as soon as the list is loaded.
So we called the
scrollIntoView method on the
ref object in
The fixed header issue while scrolling to the element
Let’s see the scrolling in action.
The header overlaps with the scrolled element, which is not visually appealing.
scroll-margin CSS property
To fix this, we can use the CSS property scroll-margin.
In React, we write CSS properties in camelCase, so
MUI provides a prop called
sx to specify styling.
We calculate the scrollMargin based on the height of the sub-header.
In this case, the height is
which is written in MUI as
where 1 spacing unit equals 8px.
Our issue is now resolved, thanks to the changes we have made.
scrollIntoViewmethod is a powerful tool that can be used to improve the user experience of our React applications.
- By using
scrollIntoView, we can make it easier for users to find the information they are looking for, and highlight important content.
scroll-marginCSS property can be used to prevent the header from overlapping with the scrolled element.
