试图在打开时更改 Bootstrap 手风琴标题的背景颜色
Trying to change the background color of the Bootstrap accordion title when opened
我正在处理这个项目，并试图在手风琴打开时更改它的背景颜色。我喜欢它关闭时是齐平的，但不喜欢它打开时的白色背景。
我也在尝试改变箭头的位置，使它们在一条直线上。
这是我目前拥有的：
console.log(1)
$(".accordion-button").click(function(){
console.log(2)
var dest = $(this).attr("data-bs-target");
$(dest)[0].scrollIntoView();
});
.accordion-button:not(.collapsed)::after {
background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='%23FEB7EE'%3e%3cpath fill-rule='evenodd' d='M1.646 4.646a.5.5 0 0 1 .708 0L8 10.293l5.646-5.647a.5.5 0 0 1 .708.708l-6 6a.5.5 0 0 1-.708 0l-6-6a.5.5 0 0 1 0-.708z'/%3e%3c/svg%3e");
}
body {
background-image: linear-gradient(rgba(143,25,154,1), rgba(200, 5, 158, 0.8));
opacity: 1;
position: relative;
overflow: scroll;
}
.accordion-title {
font-variant-caps: titling-caps;
position: absoulte;
}
.accordion-button {
font-size: 20px;
font-family: Red Rose;
color: #FEB7EE !important;
}
.accordion-button:after {
background-image: url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='%23FEB7EE'><path fill-rule='evenodd' d='M1.646 4.646a.5.5 0 0 1 .708 0L8 10.293l5.646-5.647a.5.5 0 0 1 .708.708l-6 6a.5.5 0 0 1-.708 0l-6-6a.5.5 0 0 1 0-.708z'/></svg>") !important;
