我的家＆＃34;当我压缩页面时，按钮进入div。什么是稳定按钮的最佳方法，以便在页面浓缩时它将保持在div的中心？我尝试了很多不同的东西，到目前为止没有任何工作，所以我希望这个网站上有人可以帮我解决这个问题。我没有成功地尝试了很多不同的事情。
JS / CSS / HTML
$(document).ready(function () {
//mouseenter overlay
$('ul#gallery li').on('mouseenter', function () {
// Get data attribute values
var title = $(this).children().data('title');
var desc = $(this).children().data('desc');
//validation
if (desc == null) {
desc = 'Click To Enlarge';
}
if (title == null) {
title = '';
}
//Create overlay div
$(this).append('<div class="overlay"></div>');
//Get the overlay div
var overlay = $(this).children('.overlay');
// Add html to overlay
overlay.html('<h3>' + title + '</h3><p>' + desc + '</p>');
// Fade in overlay
overlay.fadeIn(400);
});
$('ul#gallery li').on('mouseleave', function () {
//Create overlay div
$(this).append('<div class="overlay"></div>');
//Get the overlay div
var overlay = $(this).children('.overlay');
//Fade out overlay
overlay.fadeOut(200);
});

答案 0 :(得分：2)
您缺少重要的响应式元标记：
<meta name="viewport" content="width=device-width, initial-scale=1">
但您使用的是Bootstrap，它是一个响应式框架。因此，您的问题的答案是学习和理解Bootstrap，以及更广泛地研究网站响应的含义。
答案 1 :(得分：0)
使网站响应不仅仅是改变一两件事情还有很多。你真的需要计划这些元素的每个元素或容器如何以自己的方式响应。此外，您的所有内容的包装或容器的行为以及图像，文本/字体等的响应方式也将如何响应。
这个问题太过宽泛，无法简单回答。
由于您已经在使用bootstrap，我将研究如何利用它来发挥其全部潜力，并且您可以轻松地使您的网站响应。
答案 2 :(得分：0)
正如您所猜测的那样，媒体查询是一种很好的方法。
您需要在标题中添加此标记才能使用：
<meta name="viewport" content="width=device-width, initial-scale=1">
有两种方法可以设置断点 - 按最小宽度或最大宽度。
由于你已经编写了大部分样式，min-width可能更有意义。如果您有多个断点，则可以将min-width和max-width组合到单个查询中，以避免与其他媒体查询冲突。
对于主页按钮，我建议查找如何垂直居中元素。本指南非常方便：https://css-tricks.com/centering-css-complete-guide/
