如何使用按钮引导手风琴更改(,+)符号?

bootstrap-accordion bootstrap-4 twitter-bootstrap jquery javascript

SNaRe · 技术社区 · 6 年前

我在符号后面加上

但是我想用一个按钮代替它,而不是一个“-,+”符号。这样我就有了两个按钮,就像“看得更多”,“看得更少”(它可以是同一个按钮,有不同的文本和背景)然后随着我的点击而改变

我想不出来。

    content: "\f068";
    float: right; 
}
.accordion .card-header.collapsed:after {
    /* symbol for "collapsed" panels */
    content: "\f067";

在您的示例中,您使用 div.card-header 作为折叠切换;是否仅将切换触发器限制为按钮?如果是,请考虑更改 a.card-title 到 div.card-title 并添加 button 在里面。然后将css调整为 .card-header button:after . 请注意,您应该只使用 href 锚标记上的属性(在 分卡头 按钮 要使用的元素 data-target . 您可以查看 documentation here .

.accordion .card-header button:after {
    font-family: 'FontAwesome';  
    content: "\f068";
}
.accordion .card-header button.collapsed:after {
