如何居中和左对齐图像？

Question

我正在处理图片库，希望图片的容器完全居中在页面上，但图片是左对齐的。

这是我想要的输出：

但是，当我尝试在容器上执行 text-align: center 时（id：gallery），我得到的图像显示如下：

我尝试使用之前的堆栈溢出问题：CSS: Center block, but align contents to the left 并将图像包装在另一个 div 中，然后将其与 display: inline-block; 和 text-align: left; 对齐，但图像似乎在整个页面上左对齐：

我可以做些什么来完成我想要的输出？

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">

Answer 1

给你的#gallery div 一个max-width、text-align: center 和margin:auto，然后将你的标题放在#gallery 内部但#images 之外的另一个div 中。然后将text-align: left 放在您的#images div 上。

请看下面的例子：

#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">
        <img src="http://thecatapi.com/api/images/get?id=d42">
      </a>
    </div>
    <div class="container">
      <a href="http://thecatapi.com/api/images/get?id=21o">
        <img src="http://thecatapi.com/api/images/get?id=21o">
      </a>
    </div>
    <div class="container">
      <a href="http://thecatapi.com/api/images/get?id=49e">
        <img src="http://thecatapi.com/api/images/get?id=49e">
      </a>
    </div>
    <div class="container">
      <a href="http://thecatapi.com/api/images/get?id=13v">
        <img src="http://thecatapi.com/api/images/get?id=13v">
      </a>
    </div>
    <div class="container">
      <a href="http://thecatapi.com/api/images/get?id=6e6">
        <img src="http://thecatapi.com/api/images/get?id=6e6">
      </a>
    </div>
    <div class="container">
      <a href="http://thecatapi.com/api/images/get?id=4bf">
        <img src="http://thecatapi.com/api/images/get?id=4bf">
      </a>
    </div>
