HomeWeb Front-endHTML TutorialIE8下jQuery改变png图片透明度时出现的黑边问题_html/css_WEB-ITnose

png24格式的图片在用jQuery添加显示隐藏动画时发现,图片的半透明区域出现黑边?

在网上搜了搜主要有以下几种办法:

1、把图片保存成PNG-8格式。

2、把背景色一起切入并保存为JPG格式。

以上两种方法我试了试,好像效果并不好png8格式仍就会有黑边。

解决方法:

1、不要直接改变图片的透明度,而是给图片套个容器,去修改这个容器的透明度

2、给这个容器加个颜色相近的背景颜色(非常重要,解决bug的关键就在这一步,)

一般情况下,到此bug就解决了,如果还是有问题,请看下面:

3、给容器加个zoom: 1

(个人觉得这种办法只不过是一个障眼法,没有从根本上解决问题,看来目前只能这样了,期待有更好的方法)

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
