我为 friend 创建了一个网页:www.donjas-wellbeingforkids.co.uk
我直接从此处的联系页面创建了一个 Facebook Messenger 联系我们链接:donjaswell-beingforkids contact
它非常适用于台式机，可将您直接带到 Facebook Messenger，但这不适用于移动设备，因为移动 Facebook Messenger 的工作方式不同，并将您链接到应用程序。
有什么方法可以根据屏幕尺寸更改链接吗？ 下面我附上了我的 responsive.css 文件和我的 contact.html 文件。
@media screen and (min-width: 550px) {

</html>最佳答案
当然有，只需使用两个链接，如下所示:
<li class="facebook desktop"><a href="https://www.facebook.com/messages/t/1724861014479447" target="_blank">CLick to Message me on Facebook!</a></li>
<li class="facebook mobile"><a href="https://www.facebook.com/messages/t/1724861014479447" target="_blank">CLick to Message me on Facebook mobile website!</a></li>
并向 css 添加媒体查询以隐藏/显示类
@media (max-width: 600px) {
.desktop {
display: none;
}
}
@media (min-width: 601px) {
.mobile {
display: none;
}
}
关于html - 我可以根据屏幕尺寸用另一个链接替换网页上的链接吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45799724/
