Web tips and problems (HTML, CSS, JS)

1. textarea length and width settings

Method 1: Use Cols and rows

<Textarea rows = "3" Cols = "20"> </textarea>

Disadvantage: it cannot be modified after setting (JS cannot be modified), and the size of IE and Firefox is different.

Method 2: Use width and height.

<Textarea style = "width: 160px; heith: 60px"> </textarea>

2. Automatic line feed of table content

Use style = "word-break: Break-all"
Textarea is added to table TD, and the width is set to 100%. textarea is automatically opened. Add the above to table.
