CSS: Creating textured backgrounds
提问by CodingWonders90
I am currently struggling with setting an image background for my site that will load fast enough. I have used data url image and even optomized images but its taking to long when loading the page since the backgournd-image is still very large. Is it possible with CSS to create a textured background color like the one in the picture below? here is an EXAMPLE
我目前正在努力为我的网站设置一个加载速度足够快的图像背景。我使用过数据 url 图像，甚至优化图像，但加载页面时需要很长时间，因为 backgournd-image 仍然非常大。是否可以使用 CSS 创建如下图所示的带纹理的背景颜色？这是一个例子
I try it and have not been able to match this:

with latest CSS3 technology, it is possible to create textured background. Check this out: http://lea.verou.me/css3patterns/#
使用最新的 CSS3 技术，可以创建带纹理的背景。看看这个：http: //lea.verou.me/css3patterns/#
but it still limited on so many aspect. And browser support is also not so ready.
但它仍然在很多方面受到限制。浏览器支持也没有那么好。
your best bet is using small texture image and make repeat to that background. you could get some nice ready to use texture image here:
您最好的选择是使用小纹理图像并重复该背景。你可以在这里得到一些很好的准备使用纹理图像：

You should try slicing the image if possible into a smaller piece which could be repeated. I have sliced that image to a 101x101px image.
如果可能，您应该尝试将图像切成可以重复的较小部分。我已将该图像切片为 101x101px 图像。
CSS:
CSS：
body{
background-image: url(SO_texture_bg.jpg);
background-repeat:repeat;
}
But in some cases, we wouldn't be able to slice the image to a smaller one. In that case, I would use the whole image. But you could also use the CSS3 methods like what Mustafa Kamal had mentioned.
但在某些情况下，我们无法将图像切成更小的图像。在这种情况下，我会使用整个图像。但是您也可以使用 Mustafa Kamal 提到的 CSS3 方法。
Wish you good luck.
祝你好运。

If you search for an image base-64 converter, you can embed some small image texture files as code into your @import url('')section of code. It will look like a lot of code; but at least all your data is now stored locally - rather than having to call a separate resource to load the image.
如果您搜索图像 base-64 转换器，您可以将一些小的图像纹理文件作为代码嵌入到您@import url('')的代码部分中。它看起来像很多代码；但至少您的所有数据现在都存储在本地 - 而不是必须调用单独的资源来加载图像。

When I take a file from my own inventory of a simple icon in PNG format, and convert it to base-64, it looks like this in my CSS:

With your texture images, you'll want to employ a similar process.
对于纹理图像，您需要采用类似的过程。

Use an image editor to cut out a portion of the background, then apply CSS's background-repeat property to make the small image fill the area where it is used.
使用图像编辑器剪下一部分背景，然后应用 CSS 的 background-repeat 属性使小图像填充使用它的区域。
In some cases, background-repeat creates seams where the image repeats. A solution is to use an image editor as follows: starting with the background image, copy the image, flip (mirror, not rotate) the copy left-to-right, and paste it to the right edge of the original, overlapping 1 pixel. Crop to remove 1 pixel from the right edge of the combined image. Now repeat for the vertical: copy the combined image, flip the copy top-to-bottom, paste it to the bottom of the combined, overlapping one pixel. Crop to remove 1 pixel from the bottom. The resulting image should be seam-free.
在某些情况下，背景重复会在图像重复的地方创建接缝。一种解决方法是使用图像编辑器，如下所示：从背景图像开始，复制图像，从左到右翻转（镜像，而不是旋转）副本，然后将其粘贴到原始图像的右边缘，重叠 1 个像素. 裁剪以从组合图像的右边缘移除 1 个像素。现在重复垂直：复制组合图像，从上到下翻转副本，将其粘贴到组合的底部，重叠一个像素。裁剪以从底部移除 1 个像素。生成的图像应该是无缝的。
