How to disable resizing for textarea using plain CSS ?

The resize property allows a developer to define whether or not a UI element can be resized manually by the user.

Now suppose you have a textarea as shown below,

<textarea id="address">Some text</textarea>

you can disable resizing using the following css : (jsfiddle link / live demo)

#address{
    resize: none;
}

there are couple of more ways in which you could do the same as shown below…

textarea {
    resize: none;
}
textarea[name=address] {
    resize: none;
}
textarea[id=address] {
    resize: none;
}

Hope this helps :)
