将叠加按钮与另一个按钮对齐 div

Question

所以检查一下：

//Code for button a donde quieres ir 
//Start var
var nearby_search;
function nearby_choose(choice){
  nearby_search = choice;
}
//Overlay code
function nearby_search_on() {
  document.getElementById("nearby_search").style.display = "block";
}

function nearby_search_off() {
  document.getElementById("nearby_search").style.display = "none";
}

我正在尝试创建类似下拉菜单的东西，但更时尚。所以我决定不使用标签，而是使用 javascript 变量和按钮来实现我的目标。但关键是，当单击按钮时，我希望它变亮，使后面的一切变暗，并（最终）添加其他带有可供选择的选项的按钮。上面的片段是我的（错误的）方法。例如，我实际上使用两个按钮来尝试模拟几乎相同的“¿a donde quieres ir”按钮的颜色变化。我怎样才能响应地对齐这两个按钮？什么是最干净的方式来完成我想要的整体？如果有任何帮助，我将不胜感激:)

我觉得你可以用一个按钮，把它和背景分开，然后用'z-index'把按钮放上去

function nearby_search_toggle() {
    var tmpDisplay = document.getElementById("tmpBg");
    var tmpBtn = document.getElementById("tmpBtn");
    if (tmpDisplay.style.display == 'block') {
        tmpDisplay.style.display = "none";
        tmpBtn.classList.remove('active');
    } else {
        tmpDisplay.style.display = "block";
        tmpBtn.classList.add('active');
    }
}

body {
    background-color: #FCF7F8;
    font-size: 62.5%;
    height: 100%;
    margin: 0px;
}

p {
    margin-block-start: 0rem;
    margin-block-end: 0rem;
}

h1 {
    margin-block-start: 0rem;
    margin-block-end: 0rem;
}

.domainhome {
    font-family: biolinum;

    border: none;
    cursor: pointer;
    outline: none;
    margin-top: 2rem;
    margin-left: 5rem;
}

a:link {
    color: #1D263B;
    background-color: transparent;
    text-decoration: none;
