Dynamically Expandable HTML Text Input Field Using CSS
When creating text input fields, you can specify their initial size using CSS. However, you may want the field to automatically expand as you type, up to a defined maximum width.
Achieving Expandability with Content Editable
One approach to create an expandable text input field without JavaScript is by using Content Editable. This method involves:
<code class="css">span { border: solid 1px black; } div { max-width: 200px; }</code>
<code class="html"><div> <span contenteditable="true">sdfsd</span> </div></code>
How it Works:
In this solution, the span element is contenteditable, allowing users to directly edit its text. As you type, the span's width expands within the maximum width set by the div (in this case, 200px). The border of the span visually indicates the text input area.
Note on Content Editable:
While this method provides a no-JavaScript solution, it's important to note that contenteditable elements can allow users to paste HTML elements. Consider this when choosing this approach.
