TLDR

Inside a <textarea>, any text placed up to its closing tag serves as the default value:

<textarea name='comments' rows='10' cols='30'>This is the default text.</textarea>

The text nested between <textarea>...</textarea> will appear as soon as the page is loaded and can be modified by users.

Go beyond basics

Understanding the behavior of <textarea> in greater detail can further empower your web forms:

  • Placeholder Text: Utilize the placeholder attribute for instructional text that disappears when user starts typing.
<textarea placeholder="Start typing here..."></textarea>
  • Form Management: Include the name attribute to ensure form data is correctly processed.
<textarea name="feedback"></textarea>
  • Note of Warning: <textarea> does not support the value attribute. Trying to use value might lead to unnecessary confusion and errors!

Adding dynamic defaults

You might need to set default text that's not static. For such scenarios, consider:

  • Angular.js: ng-model coupled with ng-init or within a controller can dynamically bind and set default values:
<textarea ng-model="greeting" ng-init="greeting='Hi there, Angular!'"></textarea>
  • Handlebars.js: Handlebars expressions {{dynamicContent}} can inject dynamic data into the textarea:
<textarea>{{userData}}</textarea>

Each of these approaches provides dynamic strategies for those scenarios where static defaults are insufficient.

Styling textarea

  • Rows and Columns attribute to control textarea's visible size:
<textarea rows='5' cols='50'>Look! I can fit more content.</textarea>
  • With styling, <textarea> can be better integrated into the UI aesthetics:
textarea { border: 1px solid #D3D3D3; font-family: 'Comic Sans MS', 'Comic Sans', cursive; /* because we all love Comic Sans, right? 😉 */ }

Both strategies ensure that <textarea> isn't just functional but also visually pleasing!
