White to transparent gradient with background image
提问by Craig
I need to apply a white to transparent gradient which covers about a 1/4 of the top of the page and a background image visible for the rest of the page.
我需要应用一个白色到透明的渐变，它覆盖页面顶部的大约 1/4 和页面其余部分可见的背景图像。
Im looking to achieve a seamless blend from a gradient to a textured image and to do this in CSS3.
我希望实现从渐变到纹理图像的无缝混合，并在 CSS3 中做到这一点。
