title: A plain-text & single-line contenteditable div
body: <p>I am trying to make a “single-line” and “plain-text” <code>contenteditable</code> div. In other words, I just want to make a <code>&lt;input type="text"&gt;</code>, but not present in this form. How can I use the form of <code>contenteditable</code> <code>div</code> to present the form of <code>&lt;input type="text"&gt;</code>?</p>
