【解决方案2】：

您可以将display:flex 和justify-content:center 添加到按钮的容器中：

* {
  box-sizing: border-box;
}

body {
  font: 15px/1.5 Arial, Helvetica, sans-serif;
  padding: 0;
  margin: 0;
  background-color: #fff;
}

/* Global */
.container {
  width: 100%;
  margin: auto;
  overflow: hidden;
  border: 1px solid red;
}

.container .container{
  display:flex;
  justify-content: center;
}

button {
  background-color: #ff5f49;
  border: none;
  padding: 15px;
  color: #fff;
  font-size: 1.2em;
}

/* Navigation */

header {
  background-color: #353c42;
  min-height: 75px;
  text-align: center;
  font-size: 1.3em;
}

nav ul li {

  <header>
    <div class="container">
      <nav>
        <ul>
          <li><a href="">Home</a></li>
          <li><a href="">Services</a></li>
          <li><a href="">Our Work</a></li>
          <li><a href="">Contact</a></li>
        </ul>
      </nav>
    </div>
  </header>

  <section id="jumbotron">
    <div class="container">
      <img src="img/KreativeZ_logo.png" alt="KreativeZ Logo">
      <div class="container">
      <button class="button-1" type="button">Get in touch!</button>
      <button class="button-1" type="button">See Our Work</button>
