Here is the code for the menu(jQuery, CSS, HTML):
$(window).resize(function() {
// styling pro header
var winW = $(window).width();
var menuW = $('.fixedNav ul').width() + $('.fixedNav span').width() + 10;
$('.fill').width(winW - menuW);
});
$(window).resize();

- 白色菜单后面是渐变背景
- 链接在悬停时会获得透明背景,使渐变背景可见,并且这个可见部分的颜色必须始终与上面的blueLine div的颜色相对应(其具有相同的渐变背景)。 然而,上述解决方案使用了Javascript(在调整大小时计算div.fill的宽度),这是不可取的,因为这会导致页面刷新时出现闪烁,原因是javascript加载在css之后。 我的问题是如何仅使用CSS实现相同的效果。 谢谢。
