如何创建英雄形象

步骤1）添加HTML：

示例

<div class="hero-image">
<div class="hero-text">
    <h1>I am John Doe</h1>
    <p>And I'm a Photographer</p>
    <button>Hire me</button>
</div>
</div>

步骤2）添加CSS：

示例

body, html {
    height: 100%;
}

/* The hero image */
.hero-image {
/* Use "linear-gradient" to add a darken background effect to the image (photographer.jpg). This will make the text easier to read */
background-image: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url("photographer.jpg");

/* Set a specific height */
height: 50%;

/* Position and center the image to scale nicely on all screens */
background-position: center;
  background-repeat: no-repeat;
background-size: cover;
position: relative;
}

/* Place text in the middle of the image */
.hero-text {
text-align: center;
position: absolute;
  top: 50%;
left: 50%;
  transform: translate(-50%, -50%);
  color: white;
}
