Bootstrap按钮点击会出现边框的调整

如果不需要Bootstrap按钮组件、页码组件点击后会出现边框，可以在需要去除的页面或者css文件加入如下代码，实际按照你的class名调整：

.btn:focus,
.btn:active:focus,
.btn.active:focus,
.btn.focus,
.btn:active.focus,
.btn.active.focus {
    outline: none !important;
    box-shadow: none !important;
}

.page-link:focus,
.page-link:active:focus,
.page-link.active:focus,
.page-link.focus,
.page-link:active.focus,
.page-link.active.focus {
    outline: none !important;
    box-shadow: none !important;
}
