DIV+CSS，如何使DIV跟随窗口大小改变位置，跟随住某个点击显示的图标

夺命奇犽 2014-05-31 04:36:56

手头有以下代码，是给某个播放器添加一个新的图标功能，设置了一个隐藏的DIV并加上CSS，点击显示，点其他地方隐藏。
但是这个DIV，不随窗口大小变化跟随到图标旁边，一直固定到了1081px。一缩小窗口，点击后就看不见了，除非将窗口拉到1081px宽度才行，但是位置却不是在图标旁边，偏移了
我希望他能想“更多”图标的DIV一样，无论窗口大小怎么样，都能出现在“更多”图标的旁边。
而且我发现“更多”图标的DIV的"element.style"内联样式的"left"也是跟着窗口变化的，而我的貌似是定死的。



//调用函数把CSS样式添加到<head>段的 <style>元素中

function addGlobalStyle(css) {

	var head, style;

	head = document.getElementsByTagName('head')[0];

	if (!head) { return; }

	style = document.createElement('style');

	style.type = 'text/css';

	style.innerHTML = css;

	head.appendChild(style);

}



//定义CSS样式
