html - CSS 按钮位置

Question

下面是我创建的联系表单的代码。当您单击预览时，会出现第二个页面 View 。是否可以将“提交”按钮设置在与“预览”按钮相同的位置？任何帮助，干杯。

function openNav() {
    var input = document.getElementById("txtDetail");
    var value = input.value;
    var label = document.getElementById("labelDetail");
    label.innerHTML = value;
  
    var input = document.getElementById("txtName");
    var value = input.value;
    var label = document.getElementById("labelName");
    label.innerHTML = value;
  
    var input = document.getElementById("txtNumber");
    var value = input.value;
    var label = document.getElementById("labelNumber");
    label.innerHTML = value;
    
    var input = document.getElementById("txtEmail");
    var value = input.value;
    var label = document.getElementById("labelEmail");
    label.innerHTML = value;
  
    document.getElementById("myNav").style.width = "100%";
}

function closeNav() {
    document.getElementById("myNav").style.width = "0%";
}

Answer 1

So here's the full code - 
add "collapsed" class to the html div id=myNav
toggle this class on the 2 clickHandlers (openNav and closeNav)
give the anchor tag X close a z-index: 100;
give the "collapsed" class the relevant css.
