Trying to remove resizable from textarea [duplicate]

You need to use resize property to prevent the textarea to be resized.

Demo

textarea {
   resize: none;
}

resize property also takes values like vertical and horizontal to resize the textarea horizontally only, or vertically only.

For Vertical only

textarea { 
   resize:vertical; 
}

For Horizontal only

textarea { 
   resize:horizontal; 
}
