How to use CSS sprites .megaphone {width:50px; height:50px; background:url(images/sprite.png) 0 0px;}. The above CSS code is saying the width and height of the megaphone image (50px by 50px) it is also calling the image sprite.png which is our combined image.ince we defined the width and height of the image in the CSS, the image will only display 50 pixels down the image (where the megaphone is) and will stop, thereby not displaying the smiley face at all. Now let's do the smiley face and see how that changes our code.

PNG (Portable Network Graphics) PNG (Portable Network Graphics) PNG (pronounced ping as in ping-pong; for Portable Network Graphics) is a file format for image compression that, in time, is expected to replace the Graphics Interchange Format (GIF) that is widely used on today's Internet. Owned by Unisys, the GIF format and its usage in image-handling software involves licensing or other legal considerations.

- A filename extension is an identifier specified as a suffix to the name by syntax, often separated from the base filename (by, e.g., a dot, a space), that indicates, e.g., the encoding (file format), the usage, of a computer file. Examples of filename extensions are .png, .jpeg, .exe, .dmg, and .txt. Note that some systems might have multiple types of extension, e.g., in CMS CMS EXEC A1 has two extensions, the filetype EXEC and the filemode A1.

- W3c vector graphics image file format. SVG is a file extension for a vector graphics image file format created by the W3C to describe such images by mathematical equations. SVG uses XML (Extensible Markup Language). Some existing variants of SVG in use are SVG 1.0, SVG 1.1 and SVG Tiny 1.2), SVG Tiny (SVGT) and SVG Basic (SVGB).

File Extension Search Be careful not to rename the extension on .png files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another. A file extension is the set of three or four characters at the end of a filename; in this case, .png. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically.

Portable Network Graphics Adobe Fireworks (formerly by Macromedia) uses PNG as its native file format, allowing other image editors and preview utilities to view the flattened image. However, Fireworks by default also stores meta data for layers, animation, vector data, text and effects. Such files should not be distributed directly.

Difference between PNG and JPG Examples of bitmap images include .png, .psd, .jpg, .gif, .tif, or .bmp. PNG stands for Portable Network Graphics. It was created as an improved and non-patented replacement for Graphics Interchange Format (GIF). JPG is the file format for a JPEG image. JPEG is the most commonly used format for photographs. It is specifically good for color photographs or for images with many blends or gradients.

GIF, PNG, JPG or SVG. Which One To Use? A newer file format than GIF and JPEG, the PNG (Portable Network Graphics) is like a marriage between both the GIF and JPEG format thanks to its two variants. PNG-8. PNG-8 is similar to GIF in many ways and uses the same 256 color palette (maximum). It has better transparency options and usually exports slightly smaller file sizes. However, PNG-8 has no animation function. PNG-24. PNG-24 allows you to render images with millions of colors – much like JPEG – but also offers the ability to preserve transparency. Because PNG-24 is a lossless format file type, you are likely to get larger files, but if image quality is more important than file size, PNG-24 is your best option.

GT Explains: What is the Difference Between JPG, GIF, PNG, BMP Image Formats? Like GIF, the PNG format supports 8-bit color but also extends it to 24-bits, thus giving you more color ranges to work with like in a JPEG file. PNG files do not support animation. PNG files are also lossless files retaining color information when they are compressed. Richer images will lead to larger file sizes. BMP (Bitmap)

Graphics File Format Types and When To Use Each One When to Use PNG. Use PNG when you need smaller file sizes with no loss in quality. PNG files are usually smaller than TIFF images. PNG also supports alpha transparency (soft edges) and was developed to be a Web graphics replacement for GIF. Note that if you want to retain full transparency, you will need to save your PNG file as PNG-24 and not PNG-8.

Image File Formats One version of the format, PNG-8, is similar to the GIF format. It can be saved with a maximum of 256 colours and supports 1-bit transparency. Filesizes when saved in a capable image editor like FireWorks will be noticeably smaller than the GIF counterpart, as PNGs save their colour data more efficiently.

Margins and Padding margin and padding are the two most commonly used properties for spacing-out elements. A margin is the space outside something, whereas padding is the space inside something. Change the CSS code for h2 to the following: h2 { font-size: 1.5em; background-color: #ccc; margin: 20px; padding: 40px; }. This leaves a 20-pixel width space around the secondary header and the header itself is fat from the 40-pixel width padding. The four sides of an element can also be set individually.

Difference Between JPG and PNG JPG vs PNG. When it comes to images, there are a number of formats to choose from in saving to a digital copy. Each format has its own strengths and weaknesses, and choosing the right format can be a great advantage. Two of these formats are JPG and PNG. The main difference between JPG and PNG is the compression algorithms that they use. JPG uses a lossy compression algorithm that discards some of the image information in order to reduce the size of the file. In comparison, PNG uses a lossless algorithm that keeps all the information.

CSS - Cascading Style Sheets CSS - Cascading Style Sheets. Related Terms. (1) Short for Cascading Style Sheets, a new feature being added to HTML that gives both Web site developers and users more control over how pages are displayed. With CSS, designers and users can create style sheets that define how different elements, such as headers and links, appear. These style sheets can then be applied to any Web page. The term cascading derives from the fact that multiple style sheets can be applied to the same Web page. CSS was developed by the W3C.

Digital Image File Types Explained Currently, GIF and JPG are the formats used for nearly all web images. PNG is supported by most of the latest generation browsers. TIFF is not widely supported by web browsers, and should be avoided for web use. PNG does everything GIF does, and better, so expect to see PNG replace GIF in the future.
