如何居中和左对齐图像？

我正在创建一个图像库，希望图像的容器完全居中在页面上，但图像保持对齐。

这是我想要的输出：

但是，当我尝试做一个text-align: center在容器上（id：gallery）我得到的图像显示如下：

我尝试效仿之前的堆栈溢出问题：CSS：居中块，但内容向左对齐 https://stackoverflow.com/a/31643221/4808091并将图像包裹在另一个 div 中，然后将其与display: inline-block; and text-align: left;但图像似乎在整个页面上左对齐：

我可以做什么来实现我想要的输出？

HTML

 <div id="gallery">
     <div id="images">
        <div class="container">
            <a href="images/gallery/image1.jpg" data-lightbox="mygallery">
                <img src="images/gallery/image1.jpg">           
            <div class="overlay">
                <img src="images/magnify.png">
            </div>
               </a>
        </div>
        <div class="container">
            <a href="images/gallery/image2.jpg" data-lightbox="mygallery">
            <img src="images/gallery/image2.jpg">
            <div class="overlay">
                <img src="images/magnify.png">
            </div>
            </a>
          </div>
        </div>
    </div>

CSS

#gallery{
    text-align: center;
}
#images{
    display: inline-block;
    text-align: left;
}
img{
    width: 300px;
    cursor: pointer;
}
.overlay  {
    position: absolute;
    right: 0;
    left: 0;
    cursor: pointer;
    visibility: hidden;
    color: transparent;
    top: 0;
    bottom: 0;
    width: 100%;
    height: 100%;
    transition: all ease-in .3s;
}
.overlay > img{
    height: 50%;
    width: 50%;
    top: 50%; 
    visibility: hidden;
    left: 50%;
    transform: translate(-50%,-50%);
    position: absolute;   
}
.overlay:hover > img{
    visibility: visible; 
}
.container {
    position: relative;
    display: inline-block;
    margin: 5px;
}
.container:hover .overlay  {
    visibility: visible;
    opacity: .6;
    background: black;
    color: white;   
}

给你的#gallery div a max-width, text-align: center, and margin:auto，然后将标题放入另一个 div 中#gallery，但在#images。然后放text-align: left在你的#images div.

请参阅下面的示例：

#gallery {
  text-align: center;
  max-width: 420px;
  margin: auto;
}

img {
  width: 100px;
  cursor: pointer;
}

.container {
  display: inline-block;
}

#images {
  text-align: left
}

<div id="gallery">
  <div id="header">
    <h1>Header</h1>
  </div>
  <div id="images">
    <div class="container">
      <a href="http://thecatapi.com/api/images/get?id=d42">
