I have an img menu with svg images that changes the svg image with a identical image with a different color when you push in menu. When I test it with Chrome it works fine until you visit one link the second time, that chrome resize it to a smaller image.
I've made a lot of tests... I've tested :visited css, user agent css, and many another properties and it seems to be all ok. When you changes some css property in developer tools it changes automagically to correct size.
My last test was to change the width from 135px to 134px (don't ask why) and it works in 1680x1050 screen but not in 1920x1200 screen (???????). Is it an aspect ratio problem?
I'm getting crazy!!
I'm using angularjs to make the black image to red image change, but I think this is not the problem (it does a src replacement)
You can see it in the webpage http://silviaperezcruz.com.
I'll apreciate any kind of help.
PD: Sorry for my bad english
I couldn't see an obvious reason why it is doing it,. But if I had to guess, I would cast a suspicious eye on respond.js first. Does it still do it if you remove that?

I encountered a weird Firefox's behaviour. It renders SVG images cutting parts of them or not displaying them at all, but only certain of images, not all of them. Chrome and IE are displaying them properly. Here is a link to the website I put said images on:
funjo.pl
Images which are not being displayed properly are logo in top menu bar and big blue logo with transparency on the big very top banner. The funny thing is that two icons a bit down on the same page (three rolls and woman's legs), which are also SVGs are being displayed properly. Could someone please tell me what's going on? I suppose there is something wrong with SVG image code itself but I can't detect what exactly.
I'm not pasting whole images' code beacuse it's too much of it. You can download these images from http://funjo.pl/media/2016/06/logo.svg and http://funjo.pl/media/2016/06/logo2.svg.
PS: If you really want me very badly to paste the whole code let me know.
PS2: I created all of SVGs on the website using Corel X7, if this information helps in anything.
PS3: I'm using the newest FF v 46.0.1.
Actually I've found a solution myself, it helped perfectly but required few more steps after exporting SVG in Corel X7 (as I mentioned in my post above there were two images, one of them with transparency). So here are the steps I made to make it being displayed properly in FF (a bit trial and error procedure but works):
I exported both SVGs again removing transparency from the one which was originally transparent, so no transparency at all in both SVG images. The one used as logo in menu bar contained all the elements grouped (logo and text were both separate but grouped), I ungrouped those elements and made them as one.
I removed height and width attributes from both SVGs.
I added preserveAspectRatio="none" attribute so I could manage width and height of the image separately, just like raster images (this CSS Tricks article helps a lot with understanting the whole resizing process).
I used SVG Optimiser tool to remove all the unnecessary bits from my images and to slim them down a little.
I downloaded optimised SVGs from above mentioned tool's website, uploaded them to my website's FTP.
I added height:(some)px and width:auto attributes in CSS
I added transparency for the one which was supposed to be transparent via CSS - opacity:0.7 in this case.
Refreshed the website and voilà, it works like a charm. Hope it will help someone with the similar problem as mine.
EDIT
Here are images to compare, working one and not working one.
PS: After some more trials and errors I found out that changing standard text to curves in Corel X7 makes FF render the SVG image properly without above steps, but it doesn't change the fact that it worked properly in Chrome and IE anyway even if the text wasn't changed to curves before export. Plus FF didn't display SVG exported with transparency at all and Chrome and IE did.
You could open a working and failing SVG file into your text editor and find differences in the generated HTML.
I guess there is a difference the way you save it or how the vectors and layers are put. Maybe some transparent layer on top off the image renders strange?
Applying a width of 300px or above gave me the correct results as in chrome and IE.
So just give a width as below and probably you can adjust the width as per your requirement.
Hope it helps.
<img style="width: 300px;" src="http://funjo.pl/media/2016/06/logo.svg" alt="Funjo">
I solved it by removing commas , by spaces
I created an extension for Firefox and made a simple icon for it.
But when I tested it in the Addon manager the icon appeared blurry despite my source image was fine.
I started to experiment with different sizes and shapes of the icon.
Figured out that the icon container is 48x48 pixels and the default addon icon is 32x32.
But for any experiments the result was the same.
So I created a simple rectangle icon drawing it by pixels so it shouldn't blur anyway:
But the result blurred again:
There is some sub-pixels around the rectangle though the border should be crisp...
In pixels view:
Also I found the default extension icon (a puzzle piece) and in pixels it looks perfect but in the manager the borders are blurred a little though it's not obvious at first glance.
Are you sure this is not happening when you save the image? I don't know what app you are using, but many photo apps try to compress jpm images when you save them by default. Check this first.
Usually this does not happen with png images, so you could try using a png image instead as well.
It was silly enough... The broblem was the page scale not 100% on the Addons page. Pressed Ctrl+0 and all restored.
It happens sometimes on other web pages when I zoom in/out the view and images lose their sharpness.
I am working with SVG the first time and came across this problem:
I am using some SVGs for icons and everything works fine - except for one icon that renders incorrectly in Firefox on Windows. Firefox on OS X however renders it just fine.
Here is an anonymized version of the header I am placing SVG icons in:
http://files.uiux.de/140618_header/
That problem persists regardless if I use the Sprite utilized in the above example or if I use separate files for each icon.
Here are two screenshots of the render-issue I am experiencing. The problem is that little 'dent' on the lower end of that earphone:
We've saved those SVGs in Illustrator and used SVG 1.1 as export-setting.
Can someone point out what the problem seems to be here?
I'm not seeing that error in the sample header when I look at it with my version of FF (30).
It looks to me as if the artifact/'dent' you are seeing is caused by the left-most column of pixels of the envelope icon next to the phone in the sprite sheet. You can tell if you zoom up the image.
What I do, to make sure things like this don't happen, is to not put icons hard up next to each other in the spritesheet. Leave a few pixels gap between them.
We have a sprite of many icons which is 10564px x 80px. The icons are arranged horizontally.
In every other browser except IE10 the icons/images show up when being used as background images for tags with specific CSS to apply the relevant position.
When viewed in IE10 they do not show up at all and actually when you try to view the png file directly from the URL in IE10 it doesn't show either.
Any ideas?
After extensive testing, it turns out it's a limitation on the width of the PNG canvas and IE10.
PNG images would work and can be viewed right up until 8000px wide but no more than that, after that they just don't render.
After more testing it's related to whether or not they are transparent. PNGs with transparency just don't show at all whereas images without transparency show as a black block (canvas).
Whether or not MS will fix this remains to be seen... we live in hope!
The fix for us is to reduce the width of our sprite to 8000px and have two or more rows of icons/images well spaced out.
The fixes is only to separate the each individual image as single with minimum size, which will be less than 8000px wide;
I have this website: hrrubin.dk
In chrome, you will notice that all images that have image switch on mouseover, are positioned wrong. This has flaw happened only recently. Maybe a cause of some changes to the chrome code.
Is the solution to make a chrome hack, so not to disturb the the rest of the browsers?
I think there's a better way to do it. You put all of those images in a sprite, and apply them as a background image to the a tag. Give distinct IDs to each a tag. Then use background positions to position them and to change them on hover. That's how its generally done.
