With that generic of a selector matching anything that happens to be the targetif the URL changed to end in faq and there was another element with an ID of faqthat selector would match again and the faq element would have a yellow background. Anything you could do changing a class to change state you could do when the element is in :target. The most common way is by a user clicking a link which includes a hash.
Could be an internal same-page link or a fully qualified URL that happens to end with a hash and value. For instance, I once tried a variety of techniques to replicate functional CSS tabs, but ultimately decided using the checkbox hack was a better idea because it avoids the page-jumping issues.
His third example uses :targetand absolutely positioned elements hidden above the top of the page to prevent page jumping behavior.

You can use the background-image CSS rule to apply a background image to a page or elements on a page. Here are the general steps:.
Attach the background-image style rule to the page you want to apply the image to. Tell CSS where background-image is by adding a url identifier. Use the keyword url to indicate that the next thing is an address.
Make sure you surround the URL with quotes. A lot can go wrong with background images. The image may not be in the right directory, you might have misspelled its name, or you may have forgotten the bit. Here is a page with a nice background. Unfortunately, the text is difficult to read.
Background images can add a lot of zing to your pages, but they can introduce some problems, such as. Background images can add to the file size.
Images are very large, so a big background image can make your page much larger and harder to download. Some images can make your page harder to read. An image in the background can interfere with the text, so the page can be much harder to read. A good picture draws the eye and calls attention to it. The job of a background image is to fade into the background.
If you want people to look at a picture, embed it. Backgrounds need to be low contrast. If your background image is dark, you can make light text viewable. If the background image is light, dark text shows up.

Let's consider a large image, a x Firefox logo image. We want for some reason likely involving horrifyingly bad site design to tile four copies of this image into a xpixel element. To do this, we can use a fixed background-size value of pixels. On the other end of the spectrum, you can scale an image up in the background.
Here we scale a 32x32 pixel favicon to x pixels:. Besides CSS data type represents a distance value. Lengths can be used in numerous CSS properties, such as width, height, margin, padding, border-width, font-size, and text-shadow. Let's take a look at these. The contain value specifies that, regardless of the size of the containing box, the background image should be scaled so that each side is as large as possible while not exceeding the length of the corresponding side of the container.Full Screen Background Image using CSS
Try resizing the example below to see this in action.

The background-image property in CSS applies a graphic e. The url value allows you to provide a file path to any image, and it will show up as the background for that element. This technique removes one HTTP request, which is a good thing. But, there are a number of downsides, so before you start replacing all of your images make sure you consider all the pros and cons of Data URIs. You can also use background-image to sprite imageswhich is another useful method for reducing HTTP requests.
Another option when using backgrounds is to tell the browser to create a gradient. Technically speaking, gradients are just another form of background image. The difference is that the browser makes the image for you.
The example above uses only one gradient, but you can also layer multiple gradients on top of each other. There are some pretty amazing patterns you can create using this technique.
You can specify your fallback color like this:. You can use multiple images, or a mixture of images and gradients, for your background. List the image that should be at the front first, and the image that should be at the back last, like this:. If you want to use the background shorthand, you can set the values for each image individually. Your shorthand will look something like this notice the comma separating the first image and its values from the second image and its values :.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. My CSS files are in a CSS folder, images in an Image folder, and my html pages are in many different folders depending on their content and meaning to the website. The path used in the above example is a relative path. And obviously, this path only works for some of the pages. Therefore every path is correct no matter where the file is in the folder structure!

Viewed 98k times. I have a style sheet where I include background images. All my pages inherit this css as it is the MAIN theme. Just use an absolute path everytime, ie. No need for absolute paths, this shouldn't be an issue with an external stylesheet, as paths are always relative to the stylesheet itself.

After some research, Putting a forward slash before the path to define the route only works once the website is hosted with a domain. To move forwardjust start with the first subdirectory and keep moving forward.Images are an important part of attractive website designs. This includes the use of background images. These are the images and graphics that are used behind areas of a page as opposed to images that are presented as part of the content pages.
These background images can add visual interest to a page and help you achieve the visual design that you may be looking for on a page. If you begin working with background images, you will undoubtedly run into the scenario where you want an image to stretch to fit the page.
This is especially true for responsive websites that are being delivered to a wide range of devices and screen sizes. This desire to stretch a background image is a very common desire for web designers because not every image fits in the space of a website.
Instead of setting a fixed size, stretching the image allows it to flex to fit the page no matter how wide or narrow. The best way to stretch an image to fit the background of an element is to use the CSS3 property, for background-sizeand set it equal to cover.
Now, take a look at the CSS. It's not much different than the code above. There are a few additions to make it clearer. By setting background-size to coveryou'll guarantee that browsers will automatically scale the background image, however large, to cover the entire area of the HTML element that it's being applied to. Take a look at a narrower window. According to caniuse.
It does create some problems with Microsoft browsers, so a fallback might be necessary. This method isn't perfect, and it might cause some uncovered space, but by using the background-position property, you should be able to eliminate the problem and still accommodate older browsers. The result on a full-screen browser or one with similar dimensions to the image is nearly identical.
However, with a narrower screen, the flaws start to show. This covers you for all the modern browsers available today, which means you should use this property without fear that it will not work on someone's screen.
Between these two methods, you shouldn't have any difficulty supporting nearly all browsers. As background-size: cover gains even more acceptance among browsers, even this fallback will become unnecessary.
Clearly, CSS3 and more responsive design practices have simplified and streamlined using images as adaptive backgrounds within HTML elements.
