html - Firefox throwing error while reading #hex color codes inside inline SVG -

-

this doesn't happen on chrome, happen on ff , ms edge, @ least. in ff, when try paint svg inside of css url() or object tag, if svg contains #hex color #ff0000, crash. let me show example:

<p>not using # colors</p>  <object type="image/svg+xml" data="data:image/svg+xml;charset=utf-8,<?xml version='1.0' encoding='utf-8'?><svg version='1.2' xmlns='http://www.w3.org/2000/svg' xmlns:xlink='http://www.w3.org/1999/xlink' x='0px' y='0px' width='70px' height='70px' viewbox='0 0 100 100' xml:space='preserve'><circle fill='red' cx='50' cy='54.7' r='15.72'/></svg>">    no svg utf8  </object>    <p>using #hex colors (won't show on ff)</p>  <object type="image/svg+xml" data="data:image/svg+xml;charset=utf-8,<?xml version='1.0' encoding='utf-8'?><svg version='1.2' xmlns='http://www.w3.org/2000/svg' xmlns:xlink='http://www.w3.org/1999/xlink' x='0px' y='0px' width='70px' height='70px' viewbox='0 0 100 100' xml:space='preserve'><circle fill='#ff0000' cx='50' cy='54.7' r='15.72'/></svg>">    no svg utf8  </object>

why happen? there other way in svg write colors?

a hash character in url reserved indicate start of fragment identifier.

you need url encode # %23.

it's chrome bug not enforce rule or indeed parse urls correctly.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
