有人知道如何改变Bootstrap的输入:焦点吗?当你点击输入字段时显示的蓝色辉光?
当前回答
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;
}

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.
如果你想完全移除阴影，添加类shadow-none到你的输入元素中。
最后，我在bootstrap.css中修改了以下css条目
textarea:focus,
input[type="text"]:focus,
input[type="password"]:focus,
input[type="datetime"]:focus,
input[type="datetime-local"]:focus,
input[type="date"]:focus,
input[type="month"]:focus,
input[type="time"]:focus,
input[type="week"]:focus,
input[type="number"]:focus,
input[type="email"]:focus,
input[type="url"]:focus,
input[type="search"]:focus,
input[type="tel"]:focus,
input[type="color"]:focus,
.uneditable-input:focus {
border-color: rgba(126, 239, 104, 0.8);
box-shadow: 0 1px 1px rgba(0, 0, 0, 0.075) inset, 0 0 8px rgba(126, 239, 104, 0.6);
outline: 0 none;
}
我降落到这个线程寻找方法禁用辉光完全。许多答案对我来说太复杂了。为了简单的解决方案，我只需要一行CSS如下。
input, textarea, button {outline: none; }
在Bootstrap 4中，如果你自己编译SASS，你可以改变下面的变量来控制焦点阴影的样式:
$input-btn-focus-width: .2rem !default;
$input-btn-focus-color: rgba($component-active-bg, .25) !default;
$input-btn-focus-box-shadow: 0 0 0 $input-btn-focus-width $input-btn-focus-color !default;
注意:从Bootstrap 4.1开始，$input-btn-focus-color和$input-btn-focus-box-shadow变量只用于输入元素，而不是按钮。按钮的焦点阴影被硬编码为box-shadow: 0 0 0 $btn-focus-width rgba($border， .5);，所以你只能通过$input-btn-focus-width变量来控制阴影宽度。
