这是一个比较简单实用的菜单,最重要的是他不需要引用jQuery库。菜单在垂直方向上能做到自适应,当主菜单靠近顶部,子菜单将会在下面,当主菜单靠近底部,子菜单在上面。运用Modernizr的触摸检测功能,我们可以让子菜单的响应在pc上是hover,而在触摸设备上是点击。例子中还示范了如何在宽度比较窄的情况下如何调整布局。

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
