CSS

為了把它放入上下文中，我正在嘗試制作一個蝕刻草圖游戲，其中的框?qū)⒏鶕?jù)用戶輸入改變大小，以始終填充網(wǎng)格容器。這就是為什么我不能設(shè)定一個標(biāo)準(zhǔn)的高度或?qū)挾取Ｎ以噲D根據(jù)用戶輸入創(chuàng)建一定數(shù)量的盒子。除了創(chuàng)建占據(jù)整個高度的矩形而不是盒子之外，它是有效的，并且它們根據(jù)輸入改變寬度。我正在嘗試制作可以環(huán)繞的盒子，而不是一個占據(jù)整個高度的長方形。我已經(jīng)亂七八糟的彈性包裝，不能解決它。

<body>
    <div class="header">
        <h1>Etch A Sketch</h1>
      <div class="buttons">
        <button class="clear">Clear</button>
        <form id="inputForm">

        <div class="grid"></div>
    </div>

body {
    background-color: red;
    min-height: 100vh;
    height: 100vh;
    display: flex;
    justify-content: center;
    flex-direction: column;
    align-items: center;

    margin: 0;

var form = document.getElementById("inputForm");

form.addEventListener("submit", function(e) {
    e.preventDefault();

var input = form.querySelector("input");
var boxInput = input.value * input.value;
gridContainer = document.getElementById("gridContainer");
console.log(boxInput);

gridContainer.innerHTML = "";

for (var i = 0; i < boxInput; i++) {
    var div = document.createElement("div");
    console.log(div);
    div.className = "grid";
    gridContainer.appendChild(div);

既然您說flex不是必需的，那么下面就告訴您如何使用grid:

var form = document.getElementById("inputForm");

form.addEventListener("submit", function(e) {
  e.preventDefault();

  var input = form.querySelector("input");
  var num = input.valueAsNumber;
  var boxInput = num * num;
  gridContainer = document.getElementById("gridContainer");
  gridContainer.style.setProperty('--num', num);
  //console.log(boxInput);

  gridContainer.innerHTML = "";

  for (var i = 0; i < boxInput; i++) {
    var div = document.createElement("div");
    //console.log(div);
    div.className = "grid";
    gridContainer.appendChild(div);
  }
});

body {
  background-color: red;
  min-height: 100vh;
  height: 100vh;
  display: flex;
  justify-content: center;
  flex-direction: column;
  align-items: center;
  font-family: 'Franklin Gothic Medium', 'Arial Narrow', Arial, sans-serif;
  margin: 0;
}

h1 {
  margin: 0;
}

#gridContainer {
  --num: 1;
  width: 50%;
  height: 80%;
  background-color: white;
  display: grid;
  grid-template-columns: repeat(var(--num), 1fr);
  grid-template-rows: repeat(var(--num), 1fr);
}

.grid {
  /*For testing, remove this line if you don't need it*/
  outline: 1px solid blue;
}

.header {
  display: flex;
  flex-direction: column;
  margin-bottom: 5px;
  width: 800px;
  text-align: center;
  font-size: 30px;
}

.buttons {
  display: flex;
  justify-content: space-between;
}
