在網格中對齊 Div

Question

我有 8 個div ，可以在側邊欄中進行拖放。 我想將 2 行中的 div 與每行 4 個對齊。 我有第一行的權利，但似乎無法得到其余的。 這是我的代碼：

 function allowDrop(ev) { ev.preventDefault(); } function drag(ev) { ev.dataTransfer.setData("text", ev.target.id); } function drop(ev) { ev.preventDefault(); var data = ev.dataTransfer.getData("text"); var el = ev.target; if (!el.classList.contains('dropzone')) { el = ev.target.parentNode; ev.target.remove(); } el.appendChild(document.getElementById(data).cloneNode(true)); } function openNav() { document.getElementById("mySidenav").style.width = "250px"; document.getElementsByTagName("body")[0].style.marginLeft = "250px"; } function closeNav() { document.getElementById("mySidenav").style.width = "0"; document.getElementsByTagName("body")[0].style.marginLeft= "0"; }

 #div1, #div2, #div3, #div4 { float: left; width: 55px; height: 55px; border: 1px solid black; } #div5, #div6, #div7, #div8 { position: absolute; top: 136px; float: left; width: 55px; height: 55px; border: 1px solid black; } body { transition: margin .5s; } .sidenav { height: 100%; width: 0; position: fixed; z-index: 1; top: 0; left: 0; background-color: #111; overflow-x: hidden; transition: 0.5s; padding-top: 60px; } .sidenav a { padding: 8px 8px 8px 32px; text-decoration: none; font-size: 25px; color: #818181; display: block; transition: 0.3s } .sidenav a:hover, .offcanvas a:focus{ color: #f1f1f1; } .sidenav .closebtn { position: absolute; top: 0; right: 25px; font-size: 36px; margin-left: 50px; } #main { transition: margin-left .5s; padding: 16px; } @media screen and (max-height: 450px) { .sidenav {padding-top: 15px;} .sidenav a {font-size: 18px;} }

 <div id="main"> <span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; Materials</span> </div> <div id="div1" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div2" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div3" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div4" class="dropzone" ondrop="drop(event)"ondragover="allowDrop(event)"></div> <div id="div5" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div6" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div7" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div8" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="mySidenav" class="sidenav"> <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a> <a href="#"> <img src="https://unsplash.it/50/50?image=3 " draggable="true" ondragstart="drag(event)" id="drag1" width="55" height="55"> Bricks </a> <a href="#"> <img src="https://unsplash.it/50/50?image=2 " draggable = "true" ondragstart="drag(event)" id="drag2" width="55" height="55"> Stone </a> <a href="#"> <img src="https://unsplash.it/50/50?image=1 " draggable = "true" ondragstart="drag(event)" id="drag3" width="55" height="55"> Wood </a> <a href="#"> <img src="https://unsplash.it/50/50?image=0 " draggable="true" ondragstart="drag(event)" id="drag4" width="55" height="55"> Eraser </a> </div>

雖然第一排是對的，但第二排只有一個盒子。 我怎樣才能解決這個問題？

Answer 1

你的意思是盒子像這樣對齊嗎？ 看代碼。。

 function allowDrop(ev) { ev.preventDefault(); } function drag(ev) { ev.dataTransfer.setData("text", ev.target.id); } function drop(ev) { ev.preventDefault(); var data = ev.dataTransfer.getData("text"); var el = ev.target; if (!el.classList.contains('dropzone')) { el = ev.target.parentNode; ev.target.remove(); } el.appendChild(document.getElementById(data).cloneNode(true)); } function openNav() { document.getElementById("mySidenav").style.width = "250px"; document.getElementsByTagName("body")[0].style.marginLeft = "250px"; } function closeNav() { document.getElementById("mySidenav").style.width = "0"; document.getElementsByTagName("body")[0].style.marginLeft= "0"; }

 #div1, #div2, #div3, #div4, #div5, #div6, #div7, #div8 { float: left; width: 55px; height: 55px; border: 1px solid black; } body { transition: margin .5s; } .sidenav { height: 100%; width: 0; position: fixed; z-index: 1; top: 0; left: 0; background-color: #111; overflow-x: hidden; transition: 0.5s; padding-top: 60px; } .sidenav a { padding: 8px 8px 8px 32px; text-decoration: none; font-size: 25px; color: #818181; display: block; transition: 0.3s } .sidenav a:hover, .offcanvas a:focus{ color: #f1f1f1; } .sidenav .closebtn { position: absolute; top: 0; right: 25px; font-size: 36px; margin-left: 50px; } #main { transition: margin-left .5s; padding: 16px; } .row { width:100%; display:inline-block; margin-bottom:10px; } @media screen and (max-height: 450px) { .sidenav {padding-top: 15px;} .sidenav a {font-size: 18px;} }

 <div id="main"> <span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; Materials</span> </div> <div class="row"> <div id="div1" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div2" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div3" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div4" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> </div> <div class="row"> <div id="div5" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div6" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div7" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div8" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div> </div> <div id="mySidenav" class="sidenav"> <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a> <a href="#"> <img src="https://unsplash.it/50/50?image=3 " draggable="true" ondragstart="drag(event)" id="drag1" width="55" height="55"> Bricks </a> <a href="#"> <img src="https://unsplash.it/50/50?image=2 " draggable = "true" ondragstart="drag(event)" id="drag2" width="55" height="55"> Stone </a> <a href="#"> <img src="https://unsplash.it/50/50?image=1 " draggable = "true" ondragstart="drag(event)" id="drag3" width="55" height="55"> Wood </a> <a href="#"> <img src="https://unsplash.it/50/50?image=0 " draggable="true" ondragstart="drag(event)" id="drag4" width="55" height="55"> Eraser </a> </div>

Answer 2

如果您只是將 div 分開在另一行中，它似乎工作正常

 <div id="main">
  <span style="font-size:30px;cursor:pointer" onclick="openNav()">&#9776; Materials</span>
</div>

<div id="div1" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div>

<div id="div2" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div>

<div id="div3" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div>

<div id="div4" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<div class="row2">
<div id="div5" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div>

<div id="div6" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div>

<div id="div7" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div>

<div id="div8" class="dropzone" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
</div>
<div id="mySidenav" class="sidenav">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
