Issue with concealing floated elements within a container div

I am currently facing an issue with trying to hide floated divs within a parent div, but unfortunately my code is not working as expected. Here is the code snippet:

        div.scrollarea {
            overflow: scroll;
            width: 400px;
            float: left;
        }

        div.td {                
            float: left;
            width: 100px;
            height: 20px;
            background-color: red;
        }

Here is the HTML structure:

        <div class="scrollarea">
            <div class="td">x1</div>
            <div class="td">x2</div>
            <div class="td">x3</div>
            <div class="td">x4</div>
            <div class="td">x5</div>
        </div>

The current output I am seeing can be viewed in the following link: https://i.sstatic.net/I0cH1.png

What I'm aiming for is to have all .td elements in the same row with a horizontal scroll appearing when needed.

Thank you.

If you want to conceal the elements within their container, you need to ensure that the parent element is positioned relative and the children are positioned absolute. Then, utilize the z-index property to hide the children behind the parent, like so:

#parentID{
  position: 'relative';        /* necessary */
  /* additional styles required */
}

#child_element{                /* you can use class instead of id here */
  position: 'absolute';        /* mandatory */
  z-index:-99;                 /* mandatory */
  /* additional styles required */
}

To reveal the children, simply adjust their z-index value to be greater than 0

When floating elements don't fit, they will push down until they find a spot to fit in. This may not always be at the very left of the next "row," especially if the elements above them have varying heights. However, this is not a problem in your specific example.

If you want all elements to be in one row, you must ensure that they are contained within an element that reserves enough width for them to fit together:

<div class="scrollarea">
   <div style="width: 500px;">
       <div class="td">x1</div>
       <div class="td">x2</div>
       <div class="td">x3</div>
       <div class="td">x4</div>
       <div class="td">x5</div>
   </div>
</div>
