将文本居中放置在圆圈内并淡入淡出切换无效

标签： javascript jquery html css

这是我在StackOverflow中的第一个问题。因此，请让我知道我是否没有遵循正确发布问题的规则。 ：）

[问题1]

我试图通过阅读以下帖子来解决文本以圆圈为中心的问题：

  1. Center text and container inside a circle
  2. SVG center text in circle

但是，我无法解决我的问题。我想将圆形的文本移动到圆形的中间，以使文本水平和垂直地位于圆形的中心。

[问题2]

单击“测试”按钮后，将显示隐藏的圆圈。但是，再次单击该按钮后，圆圈不会消失。

如果有人可以给我建议，我将不胜感激！ ：）

已解决！

  • 这个问题不是重复的，因为我想在使用translate（）时居中放置文本，并在“ fadeToggle（）”和“：hidden with fadeIn（）”之间混淆。

$(document).ready(function() {
  $('#test').click(function() {
    $(".options:hidden").fadeToggle();
  });
});
body {
  font-family: 'Poor Story', sans-serif;
}

#test {
  cursor: pointer;
  display: block;
  text-align: center;
  position: absolute;
  display: flex;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}

.options {
  background: #f7f7f5;
  display: none;
  text-align: center;
  vertical-align: middle;
  position: absolute;
  width: 100%;
  left: 50%;
  top: 50%;
  border-radius: 50%;
  border-style: solid;
  border-color: #F3C78D;
  width: 60px;
  height: 60px;
  font-size: 12px;
}

.options span {
  color: #000000;
  text-align: center;
  vertical-align: middle;
  position: absolute;
  width: 100%;
}

#option1 {
  transform: translate(-100%, -150%);
}

#option2 {
  transform: translate(-160%, -40%);
}

#option3 {
  transform: translate(-50%, 50%);
}

#option4 {
  transform: translate(60%, -40%);
}

#option5 {
  transform: translate(15%, -150%);
}

添加此CSS代码

top: 50%; 
left: 50%; 
transform: translateX(-50%) translateY(-50%);

到.options span以使文本居中，问题1。

从jquery语句中删除:hidden以解决您的问题2。

$(document).ready(function() {
  $('#test').click(function() {
    $(".options").fadeToggle();
  });
});
body {
  font-family: 'Poor Story', sans-serif;
}

#test {
  cursor: pointer;
  display: block;
  text-align: center;
  position: absolute;
  display: flex;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}

.options {
  background: #f7f7f5;
  display: none;
  text-align: center;
  vertical-align: middle;
  position: absolute;
  width: 100%;
  left: 50%;
  top: 50%;
  border-radius: 50%;
  border-style: solid;
  border-color: #F3C78D;
  width: 60px;
  height: 60px;
  font-size: 12px;
}

.options span {
  color: #000000;
  text-align: center;
  vertical-align: middle;
  position: absolute;
  width: 100%;
  top: 50%; 
  left: 50%; 
  transform: translateX(-50%) translateY(-50%); 
}

#option1 {
  transform: translate(-100%, -150%);
}

#option2 {
  transform: translate(-160%, -40%);
}

#option3 {
  transform: translate(-50%, 50%);
}

#option4 {
  transform: translate(60%, -40%);
}

#option5 {
  transform: translate(15%, -150%);
}
