我试图用html/css/js绘制一个围棋棋盘，但我想不出一个好的方法。这是我所做的：

#Board {position: relative; left:100; top:100; height:570; width:570;}
.Square {position: absolute; height:30; width:30; background-color:#DCB579; border-color: black; border-width: 1; border-style: solid;}

.lineh0{top:0;}
.lineh1{top:30;}
.lineh2{top:60;}
.lineh3{top:90;}
.lineh4{top:120;}
.lineh5{top:150;}
.lineh6{top:180;}
.
.
.lineh18{top:540;}

.linev0{left:0;}
.linev1{left:30;}
.linev2{left:60;}
.linev3{left:90;}
.linev4{left:120;}
.linev5{left:150;}
.linev6{left:180;}
.
.
.linev18{left:540;}

我用它们在棋盘上画正方形的方法是，我用Square类和lineh和linev类在Board元素中创建元素，这取决于正方形的位置。例如，左上角和右下角的正方形：

<div id="Board">
<div class="Square lineh0 linev0"></div>
<div class="Square lineh18 linev18"></div>
</div>

问题是围棋棋盘上有361个方块，手工输入它们并不是一种好的技巧。我的问题是什么是更好的方法？

javascript

html

css

我会这样做：

let board = document.getElementById("Board");

// each lines
for(let i = 0; i < 19; i++) {
    // each column
    for(let j = 0; j < 19; j++) {
        // create a square
        let square = document.createElement("div");
        // add the Square class
        square.classList.add("Square");
        
        // instead of class linehx
        square.style.top = 30 * i + "px";
        // or use : square.classList.add("lineh" + i);
        
        // instead of class linevx
        square.style.left = 30 * j + "px";
        // or use : square.classList.add("linev" + j);
        
        // add it to the board
        board.appendChild(square);
    }
}

.Square {
    position: absolute; 
    height:30; 
    width:30; 
    background-color:#DCB579; 
    border-color: black; 
    border-width: 1; 
    border-style: solid;
}

<div id="Board">
</div>

可能需要修改您的Square样式以获得更好的结果

我会使用flex和flex-wrap，这样你就不必单独定位每个方块了。

#board {
  width: 570px;
  height: 570px;
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  justify-content: flex-start;
  align-items: flex-start;
}

.square {
  width: 30px;
  height: 30px;
}

/* below styles for demo only */
.square:nth-child(odd) {
  background: grey;
}
.square:nth-child(even) {
  background: lightgrey;
}

<div id="board">
  <div class="square"></div>
  <div class="square"></div>
  <div class="square"></div>
