我正在嘗試將'box-shadow'css屬性添加到我正在嘗試創建的頁面中'about-section'，'portfolio-section'&'about-section' 。 但是，無論我做什麼，它似乎都不起作用。將box-shadow css屬性添加到div
這裏是我的代碼..
$(document).ready(function(){;
$(".navbar-links").click(function(){
$(".navbar-links").removeClass("active");
$(this).addClass("active");
});
var portfolio_offset = $("#portfolio-section").offset().top;
var about_offset = $("#about-section").offset().top;
var contact_offset = $("#contact-section").offset().top;
$(window).scroll(function(){
$(".navbar-links").removeClass("active");
var scrolled_offset = $(this).scrollTop();
if(scrolled_offset>=contact_offset-1)
{
$("#contact_link").addClass("active");
}
else if(scrolled_offset>=portfolio_offset)
{
$("#portfolio_link").addClass("active");
}
else
{
$("#about_link").addClass("active");
}
});
$("button").click(function(){
if(!$(this).hasClass("navbar-toggle"))
window.open($(this).val(),"_blank");
});
$("#proj_img_1").click(function(){
window.open("https://codepen.io/iamrkcheers/full/JKbqjw/","_blank");
});
