Question

我通过编辑“文森特·杜兰德的简单悬停效果”来完成此按钮。但是问题是我博客中的某些CSS重叠了。因此它没有正确地对准中间位置。我找不到它可能是哪一个。我尝试在某些地方使用！important标记。但是我想那没有成功。我需要知道在该代码中的哪里应该使用！important将按钮对齐到中间？还是我需要一个新的CSS元素来做到这一点？

使用此CSS使按钮居中对齐

<html>
    <head>
    <script src="practice2.js"></script>
        <title>Practice</title>
    </head>

    <body>
        <h1>Title</h1>
        <p>sample paragraph</p>

        <ul>
            <li>List 1</li>
            <li>List 2</li>
            <li>List 3</li>
        </ul>

        <input type="submit"  value="Call Function" onclick="myFunction()"/>
    </body>
</html>

.btn-green {
  background-color: #1AAB8A;
  position: relative;
  left: 50%;
  transform: translateX(-50%);

add one parent div and set this div  text-align: center;

Answer 4

最后，问题出在评论：（

我在CSS中使用了html注释。这就是为什么发生这种情况。感谢@CharuMaheshwari提到这一点。另外还要感谢其他3个答案。他们都工作了。

在@CharuMaheshwari的帮助下，这是我决定使用的代码。

/* Awesome button css Start */
.btn-margin {
  margin-top: 1.6rem;
  box-sizing: inherit;
  text-align: center;
}

.btn {
  -webkit-tap-high!importantr: transparent;
  border-radius: 2px;
  box-shadow: rgba(0, 0, 0, 0.14) 0 3px 3px 0, rgba(0, 0, 0, 0.12) 0 1px 7px 0, rgba(0, 0, 0, 0.2) 0 3px 1px -1px;
  box-sizing: inherit;
  color: white !important;
