css sprite offset

Am I just being paranoid? In short, when using PNG hacks, don’t use sprites. Its really good and fast if we can split simply a single image for various objects. Thanks for pointing out the further possibilities of this technique! @Brent People who are tabbing hyperlinks should be using their own CSS or disabling all CSS. Jacksonville Web Design Good Article. I have two quarks though… 1.) http://cdn.myunv.com/img/resource/sitewide/assets.sprite.png, http://www.jaredhirsch.com/coolrunnings/public_images/2593af8d3b/spriteme1.png. This really opens things up. Yep, quicker transitions is a huge benefit. You just click the part you need and it gives you the CSS you need. You really have a great way of simplifying the this process. I use this method often, but does anyone know why ie6 decides to “reload” the image every time there is a hover? Some graphics just won’t look nice this way though because of the limited color palette which is further reduced by the 4 bit alpha, large gradient areas for instance. There is no shared class between the sprites; the background-image is applied to each class. However, in a production environment where you have one team prototyping and then handing off to a development team (or handing to a client), it really isn’t practical. For a previous website I tried having three columns equal length and it was next to impossible until I used sprites for one background image. Where is the link to the css sprite generator? Thanks for putting this comparison together, it really illustrates the size and speed improvements that can be achieved with a little extra planning and work. top-left corner) of the image sprite as we have done above. Nevertheless… great article! Here we will use the same sprite image (mySprite.png) to create our navigation menu. for my site. Such as, color, background-image, display, padding, etc. Not much, but some. It’s more complicated than I had hoped. Tip: For the sake of simplicity, we have used all icons of same size, and place them closely to each other for easy offset calculation. The stylesheets would have to be done as templates, using artifacts of the imagine combining step to fill in the actual super-image coordinates. Cheers for the article, it was a great help :). And when I do get the gif to appear when applying the class to the li element, the href link in the anchor does not work. Spoiler alert: they aren’t fairies that write your stylesheets for you. The outline-offset property adds space between an outline and the edge or border of an element. I’d prefer using this method over textnodes, just easier, http://www.smashingmagazine.com/2014/03/05/rethinking-responsive-svg/. PNGs of type b/ are only produced (AFAIK) by Fireworks (Fireworks calls them PNG8). Say I’m looking for something in the header, well if you have some sort of “header.png” file, you have your nav and everything in there just like you might have a folder/directory on your server. Lucy makes a great point about sprites having trouble when font sizes scale, Definitely want to encourage people to test their designs at a variety of font sizes. I may try it out in future designs just for the heck of it though :P. I think you missed the main point – the saving is with the 9 fewer requests – avoiding 4-9 latency hits for the end user (which doesn’t depend on their connection speed) and giving your server less work to do. Connect with us on Facebook and Twitter for the latest updates. In other words, the size of all the slices combned would be less than that of the whole image, unsliced. Over my old methods of working, I reckon its saved 4-6 secs on the load time. Using a dab of JavaScript, we can actually use this same concept to create an image slider out of a single tag. I think this is because the li and a HTML elements really don’t have any content… just a background graphic, so I’m a little lost. The first value is the horizontal position, and second is the vertical position of background. Outlines differ from borders in three ways: An outline is a line drawn around elements, outside the border edge http://www.shacknews.com has been using CSS Sprites for a few years now. then at the 5th time its showing the button with its hover state as it should. JavaScript creations. Not to mention the single-request super-simple image slider with a single tag. Yeah sure, no big deal on this system I’m working on now, but the crappy old junker system I use to test IE6 is slowed to a horrible crawl by those fixes and the reason I use that crappy system to test IE6 is that I think it is representative of the type of system that most people who are using IE6 may have. What is a Sprite Sprites are two-dimensional images which are made up of combining small images into one larger image at defined X and Y coordinates. You don’t redo it, you open up your sprite graphic, make it a little taller or wider and drop the new sprite in there and resave it. They have courses on all the most important front-end technologies, from React to CSS, from Vue to D3, and beyond with Node.js and Full Stack. Back in the day of the first CSS, the browser support was minimal. Thanks for the tips! The “it would look wrong without CSS” is interesting. }. I think that I am going to make an effort to start using this. What this technique does is streamline/optimize. Perhaps a slight change in approach would work a little better: make the composite image run horizontally, rather than vertically. top-left corner of the image sprite, so there is no need to shift the background-image. Alas, element must be absolute positioned for that. Ultimately, how wonderful a service spriteme is ! It’s not as genius as the 20 image sprites you can make online, but it’s much simpler and you can assign a keyboard shortcut to it in Photoshop. One of the main reasons for slicing was *not* to trick the eyes into a faster loading experience, but rather to optimize large gifs. This reduces the overhead of having to fetch multiple images. They have courses on all the most important front-end technologies, from React to CSS, from Vue to D3, and beyond with Node.js and Full Stack. http://www.novinmarketing.com/index.aspx?Content=Web-Design, Gonna try this out like asap. It may seem counterintuitive to cram smaller images into a larger image. The following sections will describes you how to convert the simple unordered list given in example above to a spite image based navigation using the CSS. A web page with many images, particularly many small images, such as icons, buttons, etc. I’ve posted it over at InformedNetworker.Com…and I’d be happy to have you submit your article links for any future postings such as these you feel might be useful for your readership. What do you think if all images will be in one sprite, and the sprite image will be big (width x height), and used for around 50 elements, won’t that be slow for some browsers? Fireworks is the only tool which can do this in a precisely manner. The long story here: The idea of “[opening] up your sprite graphic, make it a little taller or wider and drop the new sprite in there and resave it” makes my overly anal organisational tweak rear its head. The generated CSS does not include widths or heights for the sprites. I am looking for something like this, but I also want to position the background image on the right center of the UL LI. Because this is referring to content, not design elements. The dimensional size of an image plays a role in how much memory the image will take up when being used, so the less the better. Wouldn’t larger images take longer to load? top-left corner of the image sprite is 0, and since it is placed on the 5th position so its vertical distance from the starting point of image sprite is 4 X 50px = 200px, because height of each icon is 50px. Centering… holy cow… I just spent 4 hours searching the net trying to center the list in my web… no go… I just went for a ‘hack’ to put a left margin on it… Is there a way to center this list? Good post, I’ve been using sprites for navigations and buttons for a while. I’m really only familiar with PNG-8 and PNG-24 from Photoshop. I use this technique all the time and love it. But it is of course if you optimize the whole sprite image. I've used WordPress since day one all the way up to v17, I’d just like to add that I’m using css sprites on my weblog’s current design. Personally, I couldn’t care less as long as the layout isn’t broken and there aren’t big gray boxes all over. This keeps the main sprite to a minimum size. @spiralstarez: I think you make some good points. The related posts above were algorithmically generated and displayed here without any load on my server at all, thanks to Jetpack. Thank you, leverage Jetpack for extra functionality and Local Yahoo DevNet does believe “CSS Sprites are the preferred method for reducing the number of image requests” but they have a lot of other recommendations for making fewer HTTP requests as well, besides their general list of best practices. It’s a slightly different approach though, utilizing the syntax and strengths of SVG. Will be one to bookmark and look over! If there is a lot of people who want a particular feature it will surely make it’s way to browsers faster.
