第一种米字型布局代码分享，思路首先分成四个大三角形上下左右，然后在在每个大的三角形分成两个三角形，颜色自己可以调整

第二种米字型布局代码分享

html代码如下

<div class="mbigBox">
    <div class="link-top"></div>
    <div class="link-right"></div>
    <div class="line-div"></div>
    <div class="line-div1"></div>
</div>

css代码如下

.mbigBox {
    width: 202px;
    height: 202px;
    border: 1px solid gainsboro;
    float: left;
    position: relative;
    overflow: hidden;
}
.clear {
  clear: both;
  }
.link-top {
    width: 100%;
    border-top: solid #dcdcdc 1px;
    position: absolute;
    top: 50%;
}
 
/*画一条再右边的竖线*/
.link-right {
    height: 100%;
    border-right: solid #dcdcdc 1px;
    position: absolute;
    left: 50%;
}
.line-div {
    width: 284px;
    height: 118px;
    border-bottom: 1px solid #dcdcdc;
    /* border: 2px solid #000000; */
    position: absolute;
    text-align: center;
    /*margin-left: 50%;
    margin-top: -10rem;*/
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    filter: progid:DXImageTransform.Microsoft.BasicImage(Rotation=0.45);
}
.line-div1 {
    width: 484px;
    height: 204px;
    border-bottom: 1px solid #dcdcdc;
    /* border: 2px solid #000000; */
    position: absolute;
    text-align: center;
    /*margin-left: 50%;
    margin-top: -10rem;*/
    -webkit-transform: rotate(135deg);
    -moz-transform: rotate(135deg);
    filter: progid:DXImageTransform.Microsoft.BasicImage(Rotation=0.45);
}

效果图如下

第三种canvas米字型代码分享

html代码

<canvas id='canvas'></canvas>

js代码如下
drawcanvas(){
        this.canvas = document.getElementById('canvas');
        this.ctx = canvas.getContext('2d');
    this.canvas.width = 300;
    this.canvas.height = this.canvas.width;
    var color ="black";
    //画出田字格
    this.drawGrid();
},
drawGrid(){   //画出田字格
    this.ctx.save();
    this.ctx.strokeStyle = "rgb(230,11,9)";
    this.ctx.beginPath();
    this.ctx.moveTo(3,3);
    this.ctx.lineTo(canvas.width - 3,3);
    this.ctx.lineTo(canvas.width - 3,canvas.height -3);
    this.ctx.lineTo(3,canvas.height -3);
    this.ctx.closePath();
    
    this.ctx.lineWidth = 6;
    this.ctx.stroke();
    
    this.ctx.beginPath();
    this.ctx.moveTo(0,0);
    this.ctx.lineTo(canvas.width,canvas.height);
    
    this.ctx.moveTo(canvas.width,0);
    this.ctx.lineTo(0,canvas.height);
    
    this.ctx.moveTo(canvas.width/2,0);
    this.ctx.lineTo(canvas.width/2,canvas.height);
    
    this.ctx.moveTo(0,canvas.width/2);
    this.ctx.lineTo(canvas.width,canvas.height/2);
    this.ctx.lineWidth=1;
    this.ctx.stroke();
    this.ctx.restore();
},
