I merged a set of icons into one .png file and use css background-position to show these icons on a page, because img tags make a lot more http requests.
However, I need to show every icon in 2 different sizes: 20x20, 60x60. How can I do this without creating 2 separate .png files (20x400 and 60x1200)?
I am aware of the background-size property to scale the background image, but it is introduced in css3 and IE doesn't support it before 9.0.
Is it possible without using background-size?
The best way to do this is using "font icon technology" - you can read all about this in the web. Also it is helps when you need your markup retina compatible
Since you cannot use background-size for compatibility reasons you could try having both small and large versions of the icons in the same image. How you group them is up to you, but you should do some testing whether the increased size of the image still results in an acceptable load time for your pages.
+1 for icon fonts. You can do some pretty fancy things with them e.g. http://forecastfont.iconvau.lt/
I think that you could use "background:size" property. With it, you can "visually re-scale" background image.

I'm looking for best solution how to implement .svg icons into web.
Basically, I need to implement just few icons, what I have in my .psd, so I can choose any format, but it will be nice to have vector so I've choosed .svg.
Only, the problem is that I need to change color of that picture and also I need to be sure that it will be supported on all major browsers, IE as well.
For now, I'm using tag < object > which works nicely, but I'm unsure about browser support and also I can't simply change color.
How would you solve this situation ?
The .svg icons are very small and simple, I've also thought to convert them into fonts or icons, but not sure about best workflow how to do it properly.
Also, I was thinking about using .pngs, but there is a problem with changing colors and of course "scaleabness", but if I will not find out anything, I will probably end up with this...
I personaly like working with fonts (like font awesome and so...), as they are scaleable, colorable.... and displayed everywhere
Is possible to convert and add these icons from .psd to such a format, that will be close to fonts ?
Thank you for your answers :)
Check browser support for the various ways to implement SVG at http://caniuse.com/
Common workflows:
Automatically process .svg files into icon fonts, usable in CSS, with Gulp
Automatically insert .SVG content into HTML as data URIs, with server middleware
Insert all SVG icons inline into a page and reference as SVG Symbols
Insert all icons into one SVG document as individual symbols, and refer to individually with svg 'use' - https://css-tricks.com/svg-use-with-external-reference-take-2/
So I've found a solution
I've generated my own fonts from .svg. As icons we're small, there we're no problem to work with them like fonts.
I've used

Very easy to work with, just upload your .svg, make some customisations like name of your fonts, mapping and add them into your page.
The best method is to use SVG code directly in the web browser, which is supported by almost all major web browsers. The SVG code can be easily customized with all of the CSS attributes, for example, you can use current Color for properties like fill and stroke color so that one can easily change the color of your free SVG icon from their CSS. This will also reduce the number of HTTP requests required to retrieve the image icon.
I was wondering if there is an easy way to recreate the attached image using CSS3.
I've included this image as a page background but one of the senior devs told me there is an easy way to create this image background using CSS3.
I thought the background images can be done using CSS3 for repeatable patterns. But this image doesn't have any patterns that I could see.
Is that possible for this image?
I think this is interesting as experiment, but its not pragmatic.
You can convert an image to css here. PNGs work best.
Warning though, you will get tons of lines of HTML + CSS to create this image. It will come out pixel perfect though. I will also warn you that I tried uploading it to Jsfiddle, Jsbin and Codepen - all of them would just hang. Pen loaded and I couldn't save it since it's larger than 1MB.
This is what my text editor looks like with your image converted to CSS though.
This is just for reference. Yes, you can convert to CSS, but it doesn't mean that you should. I suppose it might be useful for things like email? But not for large images.
Cheers!
Hello I have a client who's logo is RP but the 'R' is facing the other way. I have been asked if it is possible to display 'RP' every time it is mentioned on the website to appear the same as her logo, instead of 'RP'.
My initial thoughts this was not possible but I have used font-awesome icons in a similar way in titles, but never using an image. This is an example of what I mean using photoshop.
Image Link: http://imageshack.com/a/img537/4474/guj5uS.jpg
I am very wary using this method at all as it must be made responsive etc and I honestly think it is more hassle than it's worth but maybe I'm missing an easy css trick...
Your help would be much appreciated.
Many Thanks
If you can contact with a graphic designer then the designer can make a svg image for you with "RP". That svg you can easily turn to a font using online font converter if you dont have professional software.
And insert the costum font you have created on your website just like inserting font awesome and/or all other icon fonts.
Is as easy as this ... nothing else that needs to be done, but always if the "RP" is in svg format (if you have a graphic designer at your disposal, or if your client can give you the RP logo in svg format).
The simplest approach is to use an image and scale it with CSS to suitable size. For best quality in scaled size, you would create the image in SVG format (there are online tools for converting other image formats to SVG, though ideally you should use an SVG file created by the artist who designed the logo). If you need to worry about old browsers (IE 8 and older) that do not support SVG, you can perhaps set content negotiation in the server so that its sends SVG to modern browsers that announce SVG support and PNG to others. But using just SVG:
<p style="font-family: Times New Roman">This is example text that
contains the logo
<img src="http://www.cs.tut.fi/~jkorpela/upload/RP.svg"
alt=RP style="height: 0.7em">
as an embedded SVG image. The height of the image is set to
0.7em without setting width. This means that browsers will scale
the image <img src="http://www.cs.tut.fi/~jkorpela/upload/RP.svg"
alt=RP style="height: 0.7em"> so
that is roughly of the same height as uppercase letters
and does not disturb line spacing.</p>
I'm kind of sure this is not possible but I ask because it seems unbelievable.
I have some elements styled for reponsive design
img {max-width:100%;height:auto;}
but the images have to be different depending on the device (I won't load heavy wide screen images on a phone device).
Since media queries aren't supported inline, I could go for a css background solution, but background-size is not perfectly supported and honnestly it would look more like a hack.
Can anyone confirm that "widely supported device related responsive images" are not properly possible ?
Thanks
If I understand your question correctly, you are looking for a way to deliver a different image depending on the viewpoint.
Adaptive Images could be the solution you are looking for. Easy enough to setup and confirm.
A second possiblity which might give you even more control is Adapt.js . I've used it with good success on several sites. You load a small javascript file in the head of your document. This tests viewpoint width and then dependending on the results, it will send the appropriate CSS file. It has wider browser support than #media requests.
If you could live with using background images, then it would work well, and since you could specify different images for different viewpoints, you aren't up the creek with browsers that don't understand background image sizes.
Good luck!
You could try the Responsive Img jQuery plugin.
It's made to automatically create and swap in different-sized images at different breakpoints, based on the container's width.
If you already have different versions on your image created and on your server, the plugin will just swap those in at the right breakpoint sizes.
Therefore, you can create new images for all the different breakpoint sizes you want, and the plugin takes care of the rest.
It's not CSS, but it gets the job done.
2014 update
There is a nice and new technique here :
http://filamentgroup.com/lab/responsive_images_experimenting_with_context_aware_image_sizing/
It requires a small js, a 1x1px blank image, a few extra markup for img tags, and some .htaccess rules.
Seems to work fine so far.
I'm on the fence about coding about 8 social media icons on a site as either img tags or anchors with CSS background images that use sprites.
I wish I could do a poll here, but I'm interested in hearing from you all what you think is best and why?
Here's a link that addresses when it is best to use img tags versus CSS background images that use sprites:
When to use IMG vs. CSS background-image?
It specifically gives the instances when CSS with sprites are better, because CSS with sprites
are faster loading and
can be used when you only want to partially display the image.
The link I gave provides a much more complete answer (my two points were off the top of my head, I bookmarked the link above and often use it for reference).
I think, in terms of my preference, I like to use sprites. Primarily because you can put all your icons in one image file, css-move the background image to the location(s) and then the user only has to download (cache) the one file. This means less requests on your server, less files to wait for AND you can preload just the one file. And updating is easier, IMO.
Hope this helps.
