Multiple lines of input in ``

Making <textarea> efficient

<textarea> is more than just a multi-line <input>. It can adapt its size to fit the input dynamically. Add the temptation of initial point insertion without spaces and the power to craft fluid layouts with width: 100%;, and <textarea> starts to personify text usability.

Power-ups for <textarea>

Bulking up <textarea> with CSS and JavaScript gives you super control and interactive properties:

• No more clumsy size-handling: width and height in CSS become your chief architects in crafting the visual presence of <textarea>.
• The highness of Height: auto_height(this) function on onInput event has your back in real-time height adjustments during input

function auto_height(elem) {
  //Make `elem` feel like it's on a rollercoaster
  elem.style.height = '1px';
  elem.style.height = `${elem.scrollHeight}px`;
}


For practicality, attach the handle to the <textarea> and let JavaScript work its magic:

<textarea rows="1" onInput="auto_height(this)"></textarea>

Diving deeper into <textarea>

Prowess of <textarea> is endless, but here are a few tools:

Flexibility with viewport

Achieve <textarea> scale alignment with viewport by percentage-based widths in CSS. Say goodbye to rigid cols.

Initial appearance

Have a compact form by setting the rows attribute to a low value and JavaScript dynamically expanding it. This ensures accessibility and appealing starting layout.

Custom styles without tears

Form design harmony is achievable. Applying a custom CSS class to all <textarea> styles such as .auto_height { /* styles */ } ensures readability and style cohesion.
