I was asked by a visitor how he could 'stretch a background picture so that it fills the entire screen'.This article shows you how to useCSSto resize an image so that it fills either the entire browser window (if your site only has one column) or theentire column (for websites with more than one of them).

Preliminaries

As with all myCSS tutorials,you will need to know a bit ofHTMLand CSS, otherwise you will have difficulty following what I say below, to say nothing of adapting it to your website.You don't have to be an expert, but some basic familiarity is needed.

In addition, please note that when I say 'background image', I mean that the picture forms the backdrop ofa web page, or part of it, with the possibility of some foreground content overlaying it. Such an image istypically placed on a page using the background-image CSS property. Corelcad 2020 0.

A Few Ways to Scale the Background Image

The CSS property to scale a background image so that it fills all the space available is background-size.

Given that, you still need to figure out what to do if the picture, when expanded, does not fit perfectly into thesurrounding space. After all, you can't expect all your visitors to surf with a browser window openedto a perfect multiple of the dimensions of your image. New desktop mac pro.

An example may make this clearer. Let's say we want to use thesitewizard.com's logo as a background image.This is a rectangular picture measuring 202 by 42 pixels. If you were to place it into an enclosureof (say) 300 by 200 pixels and expand it proportionately, it will not scale perfectly to fit into theentire space.

There are at least 3 ways that I can think of to deal with this. Since the question asked is aboutstretching an image to fill the entire background, I will assume here that you don't want the browser'sdefault action of duplicating and tiling your picture across the entire window to fill it. (If youdo, you don't need this article, since the browser does it automatically.)

  1. Preserve Aspect Ratio, No Clipping

    If you want the picture to remain undistorted and shown in entirety, one way is toset a CSS rulesaying background-size: contain. The result of this is shown below.

    The relevant CSS code is as follows:

    #demobox {
    background-image: url(./img/logo202x42.png);
    background-size: contain ;
    background-repeat: no-repeat ;
    }

    The main rule to note is background-size: contain. It expands the image proportionately sothat it is as large as possible in the given enclosing block, yet not so large that any part of the pictureexceeds the container.

    Since the image, when resized in this way, does not cover every bit of blank space, the browser willautomatically duplicate it across the remaining area (ie, tile it). If you don't want this to happen,you can force the browser to only show one copy of the picture with background-repeat: no-repeat,which I did for the above example.

    You can, if you wish, centre ('center' if you use adifferentvariant of English) the picture. Superstring 2 pro lyric video maker 2 9 0.

    The additional CSS rule needed is:

    background-position-y: center ;

    The background-position-y: center rule centres the logo vertically. On the other hand,if your picture is taller than it is wide, you may need to use background-position-x: centerto place it in the middle along the horizontal axis instead.

  2. Preserve Aspect Ratio, Clip Overflow

    Another way is to proportionately expand the image so big that every part of the container has it as a backdrop,cutting off any portion that overflows the enclosing area.

    The above was accomplished using the following CSS rules.

    #demobox {
    background-image: url(./img/logo202x42.png);
    background-size: cover ;
    }

    In order not to leave any empty space and at the same time not distort the image, the browser has toenlarge the logo so that its shortest axis fills the corresponding side of the enclosing block. This meanshowever that the other side extends beyond the display area, and thus is clipped.

  3. Stretch to Fill Everything, Ignore Aspect Ratio

    If you don't care whether your picture looks enlongated or squashed, you can force the browserto stretch it along both its axis so that it fills the entire background area.

    To do this, I specified that the dimensions of the picture be equal to that of the container.

    #demobox {
    background-image: url(./img/logo202x42.png);
    background-size: 100% 100% ;
    }

    The first '100%' of the background-size: 100% 100% rule specifies the width, and the secondthe height. Percentages are relative to the enclosing block.

Compatibility

All current versions of the major browsers support the background-size property. Ifyour visitors use Internet Explorer, they will need at least version 9 to see its effect.
