CSS background properties let us to control the size and properties of images so that we can make responsive images for both smaller and larger screens. This in turn helps us create responsive websites.
This is the same as the background-origin property. The main difference is that background-clip CUTS the image to fit inside the box, while background-origin PUSHES the content inside the box to fit.
The CSS background property
The background shorthand CSS property sets all background style properties at once, such as color, image, origin and size, or repeat method. Component properties not set in the background shorthand property value declaration are set to their default values.
Browsers do not provide any special information on background images to assistive technology. This is important primarily for screen readers, as a screen reader will not announce its presence and therefore convey nothing to its users. If the image contains information critical to understanding the page's overall purpose, it is better to describe it semantically in the document.
Note: If one of the properties in the shorthand declaration is the bg-size property,you must use a / (slash) to separate it from the bg-position property, e.g. background:url(smiley.gif) 10px 20px/50px 50px;will result in a background image, positioned 10 pixels from the left, 20 pixels from the top, and the size of the image will be 50 pixels wide and 50 pixels high.
Background Image Property: This property specify an image to use as the background of an element. By default, the image is repeated so it covers the entire element. Syntax:
Background repeat Property: By default the background image property repeats the image both horizontally and vertically. Syntax: To repeat an image horizontally
It does not matter if one of the property values is missing, as long as the other ones are in this order. Note that we do not use the background-attachment property in the examples above, as it does not have a value.
CSS background property is used to define the background effects on element. There are 5 CSS background properties that affects the HTML elements:background-color
background-image
background-repeat
background-attachment
background-position
1) CSS background-colorThe background-color property is used to specify the background color of the element.
The background-attachment property is used to specify if the background image is fixed or scroll with the rest of the page in browser window. If you set fixed the background image then the image will not move during scrolling in the browser. Let?s take an example with fixed background image.
The CSS background property defines the initial position of the background-image for an element. It is a shorthand property for setting the background-color, background-image, background-repeat, background-attachment, and background-position CSS properties.
The background property is used to set the individual properties for background-color, background-image, background-repeat, background-attachment, and background-position. Note that order matters (although some browsers may show some leniency). Learn how to use the CSS background shorthand property in the following steps.
I'm trying to mix background-image and background-size properties in a shorthanded background property. Based on W3C documentation background-size should come after background-position property separated with an slash(/).
But this is not working! It also is not clear how to make a shorthand background property when background-size and background-position have two different values for background-position-x and background-position-y or same thing for background-size. It's not clear how the slash(/) takes place? This example is not working in my Chrome 15.
but iPhone Safari browsers weren't showing the image properly with a fixed position element. I didn't check with a non-fixed, because I'm lazy. I had to switch the css to what's below, being careful to put background-size after the background property. If you do them in reverse, the background reverts the background-size to the original size of the image. So generally I would avoid using the shorthand to set background-size.
This is the same as background-origin property. The main difference is, background-clip CUTS the image to fit inside the Box & background-origin PUSHES the content inside the box to fit.
(1) for background-position, you can also use the following syntax right 10px bottom 50px for example. You can specify the origin and the offset from the origin (this works in all the direction). Don't forget that we also have the center keyword. Also pay attention to the precentage values, it doesn't work the way you are showing it (or let's say, it's not clear enough if we see the figure). Here is a good article detailing all these: dev.to/afif/all-you-need-to-know-a...(2) you are talking about gradient after talking about background-color and you are listing it as potential value of background-color. This is wrong and can be missleading as we may think that a gradient is a color that can be applied to background-color whereas it's an image and should be applied to background-image instead. You need to move the linear-gradient part when talking about image to avoid confusion. Worth to note that everything that apply to an image also apply to a gradient.(3) I have to strongly disagree with the shorthand description you are giving because the order is not important. Simply said, there is no order and we can have any combination. If you follow the formal syntax in the MDN: developer.mozilla.org/en-US/docs/W... you will notice the use of which means any order (developer.mozilla.org/en-US/docs/W...). The only requirement when using the shorthand is the use of background-size that must follow the background-position with / (ex: top left/100px 100x, related: stackoverflow.com/a/54055521/8620333(4) background-size also accept percentage value and not only pixel value(5) background-repeat accept two values (developer.mozilla.org/en-US/docs/W...) and each one-value syntax has an equivalent (even if the two-value syntax is not very common)(6) another very important feature of background is the use of multiple background layer and you are omitting this part here. All the properties you listed accept values separated with , to define different layers.
After you place your file path or SVG code into the background-image property, you can further tweak how the background displays. You see, the great thing about using an SVG as a CSS background-image is that they can be styled with CSS background properties.
Background-image can hold multiple background image layers to achieve cool effects. To create these image layers, comma-separate each image value in a single background-image property. Then when you use any related background properties, comma-separate those varied values to coincide with the images, or instead use a single value which will apply to all images the same.
You can mix images, SVG data URIs, and CSS gradients. But you need to overlap images with transparency or take advantage of the background-blend-mode discussed above. Otherwise you will only see one background. The first image is on top of the background stack.
But managing layers across multiple properties can get messy pretty quickly. For example: What if you decide to add another image layer at the top of the layer stack but forget to update other *background-** properties?
Using the background-color property will do the same thing we did above. I know you may be asking yourself... Well, what's the difference. They will do the same thing; however using the background-color will be more specific and this can come in handy in certain situations. We'll explain this a little more down the page.
The background-image property will allow us to specify an image to be used as a background for our HTML element. In order to add a background to an element you will add the value url( '/to/image.jpg' ); to the background-image property like so:
The background-repeat property will specify whether we would like our background image to repeat. If the HTML element that you are putting your background image is larger that the image itself, you may wish to tell the background-image to repeat.
The background attachment will specify whether the background image should scroll with the page or stay fixed to the page. The CSS property background-attachment has a default value of scroll, but if we were to set this to fixed it would be fixed to the page when the user scrolls.
Using the background-position property we can specify how we where we want our background to be positioned. The background-position property takes in 2 values. The x, and y value. This can be specified in pixels or it can be specified with the following positions: left, top, right, bottom, center. 2ff7e9595c
