The task we are going to perform in this article is how do we display a text area in HTML. Let’s dive into the article for getting a clear idea on how we display text area.
HTML textarea标签定义了一个多行纯文本编辑控件。由于文本空间可以容纳无限数量的字符(通常是Courier),所以文本以固定宽度字体显示。在表单中,textarea通常用于收集用户输入,例如评论或评价。在提交表单后,表单数据中的引用将需要name属性。
Let’s look into the following examples to know more about how do we display a textarea in HTML.
