十个JavaScript页面布局技巧

1. 使用Flexbox布局：Flexbox布局是CSS3中的一个新特性，可以方便地实现灵活的页面布局，特别适合移动端页面设计。 2. 使用Grid布局：Grid布局也是CSS3中的一个新特性，可以支持复杂的页面布局，如网格、栅格、水平和垂直居中等。 3. 使用响应式设计：响应式设计能够根据设备的不同大小和分辨率自动屏幕适配，提升用户体验。 4. 使用媒体查询：媒体查询可以根据不同设备和屏幕大小调整CSS的样式和布局。 5. 使用相对单位：相对单位如em、rem和vw/vh等，可以在不同页面尺寸和设备上自适应地实现页面布局调整。 6. 使用浮动和清除浮动：使用浮动可以实现多栏布局，但需要使用清除浮动来避免布局破裂问题。 7. 使用绝对定位：绝对定位可以实现层叠布局和细微的位置调整，但需要小心地掌握布局属性，以避免超出容器的限制。 8. 使用表格布局：表格布局可以实现复杂的数据表格，但需要避免滥用，以免影响布局性能。 9. 使用栅格系统：栅格系统是一种常见的页面布局技术，可以快速实现网格和多栏布局。 10. 使用CSS网格或Flexbox工具包：有许多CSS网格或Flexbox工具包，如Bootstrap和Foundation等，可以方便地实现布局和样式的快速开发。
