internet explorer - CSS: Using raw svg in the URL parameter of a background-image in IE -


so, i'm trying this:

div {     width: 100px;     height: 100px;     background-position: center center;     background-repeat: no-repeat;     background-size: 100px 100px;     background-image: url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' width='100' height='100' style='fill:red; stroke:none'><rect x='0' y='40' width='100' height='20' /><rect x='40' y='0' width='20' height='100' /></svg>"); }

see here: http://jsfiddle.net/trxkcx41/4/

this works beautifully in current versions chrome, safari (os x , ios), , firefox. however, svg doesn't appear @ in ie 9, 10, or 11.

is because not supported in ie, or because i'm doing wrong?

[update solution]

thanks hungerstar, i've got working. summarize recommendation, needed make following changes:

  1. change data type data:image/svg+xml;utf8 data:image/svg+xml;charset=utf8 (i.e., charset= required)

  2. url encode svg. minimize url-encoding, use ' instead of " enclose attributes. so, in case, < , > needed encoded.

to, ultimately, css looked this:

    background-image: url("data:image/svg+xml;charset=utf8,%3csvg xmlns='http://www.w3.org/2000/svg' width='100' height='100' style='fill:red; stroke:none' %3e%3crect x='0' y='40' width='100' height='20' /%3e%3crect x='40' y='0' width='20' height='100' /%3e%3c/svg%3e");

ie appear support using utf8 in data uri, it's being more fussy it. see codepen blog post more details here highlights:

the author points rfc2397 , highlights:

data:[<mediatype>][;base64],<data>

the <mediatype> internet media type specification (with optional parameters.) appearance of ";base64" means data encoded base64. without ";base64", data (as sequence of octets) represented using ascii encoding octets inside range of safe url characters , using standard %xx hex encoding of urls octets outside range. if <mediatype> omitted, defaults text/plain;charset=us-ascii. shorthand, "text/plain" can omitted charset parameter supplied.

  • most browsers lenient charset= string, it's required internet explorer. means need use ;charset=utf8, instead of ;utf8,.
  • from above, "without ";base64", data (as sequence of octets) represented using ascii encoding octets inside range of safe url characters , using standard %xx hex encoding of urls octets outside range." means have percent-encode characters aren't url-safe. example, <svg> %3csvg%3e. can minimize amount of percent encoding needs done using single quotes ' instead of double quotes ".

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
