如何让我的 H1 文本出现在图像的中心？答案

【问题标题】：How can i get my H1 text to appear in the center of an image?如何让我的 H1 文本出现在图像的中心？
【发布时间】：2023-02-04 04:33:08
【问题描述】：

我的网页上有一张图片，我试图在图片中央显示文本“欢迎来到华盛顿州”，但到目前为止都失败了。我尝试使用 flexbox 和显示功能，文本将在图像上对齐，但我无法将其置于图像中心。我怎样才能让它到达文本可以对齐图像中心的位置？

-谢谢您的帮助！

【问题讨论】：

为什么不在 css 中将图像设置为背景？否则你可以使用绝对定位和 z-index

标签： html css

【解决方案1】：

尝试用 div 包装 img 和 h1，然后使用该 div 将它们放在一起。 <div class="welcome-sign"> 使用 flex-box 使其内容居中。

您可以编辑

.welcome-sign h1 {
    position: absolute;
    top: 0; /* Edit this value*/
}

垂直重新定位h1。

像这样：

div {
  background-image: url("https://upload.wikimedia.org/wikipedia/commons/a/ad/King_County_District_Court_Seal.png"); 
  height: 200px;
  width: 200px;
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  outline: 1px dotten black;
  display: flex;
  justify-content: center;
}
h1 {
  align-self: center;
}

<div>
  <h1>Hello World!</h1>
</div>

        <li>Education</li>
        <li>Sports</li>

    </div>
  </div>

  <!--Welcome Page-->
  <div class="welcome-page">
    <img src="https://cdn3.goldtag.net/web/uploads/pictures/736x536/1668352521_1667803503__750-5449.jpg">
    <h1 id="theWelcome">Welcome to Washington State</h1>
  </div>
</body>

</html>

CSS

* {
  margin: 0;
  padding: 0;
}


/*------------------------------HEADER--------------------*/

.header {
  background-color: #00843D;
  height: 125px;
  position: relative;
}

.logo img {
  height: 200px;
  width: 200px;
  position: relative;
  z-index: 1;
}

.logo {
  position: absolute;
  left: 5%;
  top: 15%;
}

.nav-links {
  text-align: right;
}

.nav-links ul {
  color: white;
  padding: 25px;
}

.nav-links ul li {
  display: inline-block;
  font-size: 35px;
  padding: 20px;
}
.welcome-page{ 
  position: relative;
  background: red;
  width: max-content;
}

#theWelcome {
    position: absolute;
    top: 50%;
    background: red;
    left: 0;
    right: 0;
    display: flex;
    justify-content: center;
    align-items: center;
}

P.S：我使用虚拟图像只是为了向您展示它是如何完成的。
