Use it however you want without doctype declaration. If there is a doctype, use input type=button
In fact, the code you write is also very clear. button is a label pair, and input type=button is an independent label
, which means that button can have child elements. For example, a picture a1f02c36ba31691bcfe87b2722de723b, and the input button can only use input type=image
