<div>
    <canvas></canvas>

div {   
    height:100%;
    width:100%;   
    background:blue;
}
canvas {
    background-color: orange;
    width:100%;
    height:100%;
}
html,body{

    width:100%;

}

Answer 1

Canvas有显示：默认为内联..当你将其更改为显示时：阻止它应该显示正常..（所有图像都是相同的情况..）

Answer 2

正如@Mag所说，你可以添加display：block或设置float属性。您还可以将overflow：hidden添加到包含canvas标记的div中。

Answer 3

css更改为：

canvas {
    background-color: orange;
    width:100%;
    height:100%;
    display:block;}
