What is the best way to control the overflow length and display only a specific amount of content at once?

Question

What is the best way to control the overflow length and display only a specific amount of content at once?

I am currently designing the homepage for a social media platform. I have around 45 dummy posts and I am looking for a way to limit the overflow in CSS so that only 5 posts are displayed at a time. Once the user reaches the bottom of those 5 posts, another 5 will be loaded onto the screen.

Below is the code snippet where I map over each post:

<div id='all-post-container' style={{position: 'absolute', top: '25%', left: '20%', backgroundColor: 'red', height: '72%', width: "54%", borderRadius: '30px', overflow: 'auto'}}>
      <Grid
        container
        direction="column"
        justifyContent="center"
        alignItems="center"
        spacing={45}
      >
      {arrayOfKeysForPost.map(key => {
          return (
            <Grid container item>
              <div id="post-container" style={{margin: '5%', position: 'absolute', width: '90%', height: '40%', backgroundColor: 'white', borderRadius: '30px', overflow: 'auto'}}>
              // Post content goes here
              </div>
            </Grid>
       )})}
      </Grid>
</div>

Here is an illustration showing how it currently looks with 45 posts... (Check the scrollbar on the right)

Answer №1

It is recommended to implement this functionality using JavaScript, fetching 5 posts initially and dynamically appending the next 5 as you scroll to the bottom of the page. However, if you prefer using CSS, you can leverage the pseudo selector nth-child.

your-component-className:nth-child(n+5) {
  display: none;
}

You can then update the number 5 with JavaScript once you reach the last post in the list.

The nth-child selector will hide posts starting from the fifth one.

There are several methods to accomplish this:

To hide all overflow content (assuming you do not want this), simply include overflow: hidden; in your CSS file.

#all-post-container {
    overflow: hidden;
}

Loading the elements using jQuery You can load elements from a separate .html file. You could create one for each avatar and use the following code:

let post-max-count = 20
let posts = /* Use an npm package or module to retrieve all files in your user avatars directory as an array */
for (let _ = 0; post =  posts[_], _++) {
    if (_ < post-max-count) {
        $("#all-post-container").load(post)
    } else {
        break
    }
}

At the moment, I cannot think of any other ways to achieve this. However, I may come up with more solutions later on.
