html - 几张带标题的图片

Question

我有一个带图像的背景，在这个背景中我有 3 个图像和 3 个数字。我想为每个数字，将数字与图像居中。
我被属性 margin-left

困住了

.background-picture-red{
  height: 130px;
  width: 100%;
  position: absolute;
  background-image: url(https://i.ibb.co/jVWdfG4/bg-2.jpg);
}

.picture01{
  border: 1px solid #fff;
  padding: 10px;
  border-radius: 50%;
  background-color: rgba(224,0,0,0.30);
  float:left;
  margin-top: 10px;
  margin-left: 50px;
  z-index: 1;
  position: relative;
}

.picture01-title{
  font-family: 'Questrial', sans-serif;
  font-size: 16px;
  color: white;
  margin-left: 50px;
  margin-top: 100px;
  position: absolute;
}

.picture02{

Answer 1

这是我在每个标题中添加的一个工作示例:

  margin-left: -43px;
  transform:translateX(-50%);

• margin-left: -43px : 因为你的图片大小是86px 所以-43px会放在图片中间
• translateX(-50%) :因此文本将根据其自身的大小居中

.background-picture-red{
  height: 130px;
  width: 100%;
  position: absolute;
  background-image: url(https://i.ibb.co/jVWdfG4/bg-2.jpg);
}

.picture01{
  border: 1px solid #fff;
  padding: 10px;
  border-radius: 50%;
  background-color: rgba(224,0,0,0.30);
  float:left;
  margin-top: 10px;
  margin-left: 50px;
  z-index: 1;
  position: relative;
}

.picture01-title{
  font-family: 'Questrial', sans-serif;
  font-size: 16px;
  color: white;
  margin-left: -43px;
  transform:translateX(-50%);
  margin-top: 100px;
  
  position: absolute;
}

.picture02{
  border: 1px solid #fff;
  padding: 10px;
  border-radius: 50%;
  background-color: rgba(224,0,0,0.30);
  float:left;
  margin-top: 10px;
  margin-left: 60px;
  z-index: 1;
  position: relative;
}

.picture02-title{
  font-family: 'Questrial', sans-serif;
  font-size: 16px;
  color: white;
  margin-left: -43px;
  transform:translateX(-50%);
  margin-top: 100px;
  position: absolute;
}

.picture03{
  border: 1px solid #fff;

  margin-top: 10px;
  margin-left: 70px;
  z-index: 1;
  position: relative;
}

.picture03-title{

但也许你应该使用 flexbox做那种事。
