防止逐步(逐行)加载背景图片 [英] Prevent progressive (line by line) loading of background image

问题描述

我正在寻找一种方法来加载背景图像(CSS)，就像它们一旦加载就出现一样，而不是向下滚动".我宁愿让图像在一闪之后延迟300毫秒出现，而不要让图像看起来像是不良的PowerPoint效果.

I am looking for a way to have the background-images (CSS) load as if they were appearing once loaded, and not "rolling down". I'd rather have an image appear 300ms late in one flash instead of having it appear like a bad PowerPoint effect.

除缓存外，可以使用任何技术或特定代码吗?

Any techniques or specific code that could be used (besides caching)?

谢谢

推荐答案

首先，如果您的图片出现在向下滚动"中，则该图片太重了.

First, if your image appear in "rolling down" it's Image it's too heavy.

存在其他程序或网站，以减少您的网络形象(而不会降低质量) 例如， Yahoo SMUSH.IT！很好！

Exist different program or website for reduce your image for web ( without losing quality ) for sample, Yahoo SMUSH.IT! is good for that!

之后，我不知道是否存在下载后出现背景图像的方法……也许是在JavaScript中……

After, I don't know if existing a method for appear background-image after download... maybe in JavaScript...
