我正在一个类似页面的应用程序网站上,该网站具有用户可以单击的项目列表,以获取有关该项目的更多信息。在移动版本上,我希望此信息以模式方式弹出,但在桌面版本(大屏幕)上,我希望该信息填充内容区域的中央/右侧部分。
我已经考虑了几件事,但是它们似乎都有些混乱:使用带屏幕的@media去除(归零)或添加模态和div样式,使用javascript删除/添加模态类,具体取决于屏幕尺寸。当它们工作时,我想知道是否有一种方法可以使用CSS干净地做到这一点,以便其他javascript正常运行,而无需执行诸如在更新div(或触发模式)之前检查屏幕大小的事情。
答案 0 :(得分:0)
尝试使用此代码。
这是jsfiddle link
