Frequently Asked Questions

网页设计常用的占位图尺寸有哪些?

常见尺寸:首屏/横幅(1920x600或1200x400)、博客缩略图(800x450或16:9)、头像(150x150或200x200)、商品卡(400x400或300x300)、社交分享图(Open Graph用1200x630)。

占位图应该用PNG还是SVG格式?

SVG是占位图的理想选择,因为它与分辨率无关且文件极小(通常不到1KB)。开发时用SVG快速加载。当需要光栅图像测试图像处理流程或特定像素尺寸时使用PNG。

这些占位图可以用于生产环境吗?

可以,但它们主要用于开发和设计样稿。在生产环境中应替换为实际内容。生成的图像是带文字的纯色矩形,适合线框图和原型设计。
