what size background image works best? I have tried over 100 images and gifs, and they all get stretched, and blurry. usually 1/2 the image isn’t even viewable
You’re going to want something fairly large in dimension and in a landscape orientation (but watch out for file size too, you don’t want to force everyone to download a huge image).
For example, I accidentally took this photo of my couch. The dimensions are 1920 x 1440 and it fits my screen as a background image (text is unreadable over it, but that’s a separate issue).
Note that the image is set to background-size: cover; by default — so this means that the image will be scaled-up to fill the entire browser window without repeating the image (and likely cropped somewhat unless my window is in the same 4:3 ratio as the image). Small images will be sized up proportionately until they fit the entire window. You can change this behavior using CSS for the category, for example:
body.category-example {
background-size: 25%:
}
Now your background image is much smaller, and tiled to fill the screen.
You’ll want to work with background-size, background-repeat, and background-position in your site’s CSS to find out which properties will work for your specific image.
Can we add this tip to the UI for the feature, somewhere?
All of your CSS is controlled under admin > customize > themes, by “CSS for the category” I meant that you can target a specific category because we add CSS classes to the page when relevant.
So in the case of a category named “Other” we add the .category-other class to the page’s body tag, so you can use something like this in your general customizations to target that specific category.
body.category-other {
// your CSS for the category here
}
类别背景(例如宽度)的推荐尺寸是多少?
另外,类别图片的推荐尺寸是多少?
两者都因你想要实现的效果而有很大差异……
对于背景图片……在保持文件大小合理的前提下(比如 150KB 左右?可以使用 https://tinypng.com/ 这样的服务来减小文件大小),尽可能宽一些。宽度大概在 1440px 到 1920px 之间……
对于分类标志或图片,我个人喜欢正方形,大约 150px 左右……但如果你在其他方面自定义了布局,那么任何尺寸或方向都可以很好地工作。
由于该网站存在一些限制,我有时也会使用 https://pngquant.org/。它提供可执行文件,能在没有这些限制的情况下完成同样的工作,而且我认为它使用了相同的压缩方法。
