Dynamically Expanding Input Field with CSS and Content Editable

The ability to modify the length of a text input field as the user types presents a practical challenge. While CSS can be utilized to set the initial input size, achieving dynamic expansion without JavaScript or jQuery can be intricate.

One approach is to leverage Content Editable and CSS. Content Editable allows users to edit text directly within an HTML element. Here's an example of how it can be implemented:

CSS:

<code class="css">span 
{
    border: solid 1px black;
}
div 
{
    max-width: 200px;   
}</code>

HTML:

<code class="html"><div>
    <span contenteditable="true">sdfsd</span>
</div></code>

This configuration creates a div container with a maximum width of 200px and a span element within the container. The span is set as Content Editable, allowing users to type directly within it. As text is entered, the span's width expands dynamically up to the maximum width of the container.

Note Regarding Content Editable:

It's important to consider that Content Editable enables users to paste copied HTML elements within the element. This may not suit all use cases, so it should be taken into account when opting to use this method.
