我正在創建一個簡單的佈局。只要我點擊搜索導航欄重疊側欄滾動條。我怎樣才能解決這個問題 ？。CSS：我如何阻止重疊滾動條的固定導航欄？
下面是代碼
$('document').ready(function() {
$('.search-icon').click(function() {
var search_form = $('.search-form');
if(search_form.hasClass("form-open"))
{
// form is open, close the form
$('.search-form').toggle();
$('.search-form').removeClass("form-open");
}
else
{
// open the form
$('.search-form').toggle();
$('.search-form').addClass("form-open");
}
});
});
