改变引导输入焦点蓝色发光

你可以这样修改.form-control:focus颜色而不改变引导样式:

快速修复

.form-control:focus {
        border-color: #28a745;
        box-shadow: 0 0 0 0.2rem rgba(40, 167, 69, 0.25);
    }

完整的解释

Find the bootstrapCDN version that you are using. E.g. for me right now is 4.3.1: https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.css Search for the class you want to modify. E.g. .form-control:focus and copy the parameters that you want to modify into your css. In this case is border-color and box-shadow. Choose a color for the border-color. In this case I choose to pick up the same green the bootstrap uses for their .btn-success class, by searching for that particular class in the bootstrap.css page mentioned in the step 1. Convert the color you have picked to RGB and add that to the box-shadow parameter without altering the fourth RGBA parameter (0.25) that bootstrap has for transparency.

试试这个，它和bootstrap的输入是一样的…

input:focus{
  color: #212529;
  background-color: #FFF;
  border-color: #86B7FE;
  outline: 0;
  box-shadow: 0 0 0 .25rem rgba(13, 110, 253, .25);
}

为body标签添加一个Id。在你自己的Css(不是bootstrap.css)中指向新的body ID，并设置你想要覆盖的类或标记以及新的属性。现在您可以随时更新引导，而不会丢失您的更改。

html文件:

  <body id="bootstrap-overrides">

css文件:

#bootstrap-overrides input[type="text"]:focus, input[type="password"]:focus, input[type="email"]:focus, input[type="url"]:focus, textarea:focus{
  border-color: red;
  box-shadow: 0 1px 1px rgba(0, 0, 0, 0.075) inset, 0 0 8px rgba(126, 239, 104, 0.6);
  outline: 0 none;
}

简单的一个

要移除它:

.form-control, .btn {
    box-shadow: none !important;
    outline: none !important;
}

来改变它

.form-control, .btn {
    box-shadow: new-value !important;
    outline: new-value !important;
}

你可以使用.form-control选择器来匹配所有输入。例如改为红色:

.form-control:focus {
  border-color: #FF0000;
  box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(255, 0, 0, 0.6);
}

把它放在你的自定义css文件中，并在bootstrap.css之后加载它。它将适用于所有输入，包括文本区域，选择等…
