我正在使用nth-child选择器为不同的社交图标添加背景图像.但是,所有图标看起来都是一样的.我究竟做错了什么？
.social-logo {
display: inline-block;
width: 24px;
height: 24px;
transition: background-image .2s;
}
#social-links div:nth-child(1) {
background-image: url('https://mysql-raigovind93.c9users.io/Cally%20Dai//img/footer/logo-linkedin.svg');
}
#social-links div:nth-child(1):hover {
background-image: url('https://mysql-raigovind93.c9users.io/Cally%20Dai//img/footer/logo-linkedin-copy.svg');
}
#social-links div:nth-child(2) {
background-image: url('https://mysql-raigovind93.c9users.io/Cally%20Dai//img/footer/logo-dribbble.svg');
}
#social-links div:nth-child(2):hover {
background-image: url('https://mysql-raigovind93.c9users.io/Cally%20Dai//img/footer/logo-dribbble-copy.svg');
}
#social-links div:nth-child(3) {
background-image: url('https://mysql-raigovind93.c9users.io/Cally%20Dai//img/footer/logo-email.svg');
}
#social-links div:nth-child(3):hover {
background-image: url('https://mysql-raigovind93.c9users.io/Cally%20Dai//img/footer/logo-email-copy.svg');
}
#social-links div:nth-child(4) {
background-image: url('https://mysql-raigovind93.c9users.io/Cally%20Dai//img/footer/logo-insta.svg');
}
#social-links div:nth-child(4):hover {
background-image: url('https://mysql-raigovind93.c9users.io/Cally%20Dai//img/footer/logo-insta-copy.svg');
}
所述nth-child选择器计数的兄弟姐妹(即,具有相同的父元素).
在您的HTML结构中,div.social-logo始终是第一个,最后一个和唯一的孩子a.所以nth-child只有一个元素可以统计.
但是,有多个锚元素,所有这些都是兄弟姐妹(孩子们#social-links),所以nth-child可以针对每个元素.
#social-links a:nth-child(1) div
#social-links a:nth-child(2) div
#social-links a:nth-child(3) div
