In accordance to Google’s PageSpeed Insights, minimizing HTTP requests is important for show. Nevertheless, excessively ample CSS records-data tin besides negatively contact burden instances. Uncovering the correct equilibrium is indispensable.

Browser Compatibility and Maintainability
Base64 encoding enjoys fantabulous browser compatibility, supported by each contemporary browsers. Nevertheless, older browsers similar Net Explorer eight had limitations connected the dimension of information URIs, which may origin points. Piece these browsers are little prevalent present, compatibility is inactive a information for initiatives concentrating on older techniques. Sustaining CSS containing ample Base64 strings tin go cumbersome. Updating an representation requires re-encoding and changing the full drawstring, which tin beryllium mistake-susceptible.

Separating contented (HTML), position (CSS), and behaviour (JavaScript) is a cornerstone of internet improvement. Piece Base64 blurs these strains somewhat, utilizing it judiciously for tiny belongings does not importantly break this rule.
Alternate options to Base64 for Inheritance Photographs

Question & Answer :
I was trying astatine the origin of a greasemonkey userscript and seen the pursuing successful their css:
.equal { inheritance: #fff url(information:representation/gif;base64,R0lGODlhBgASALMAAOfn5+rq6uvr6+zs7O7u7vHx8fPz8/b29vj4+P39/f///wAAAAAAAAAAAAAAAAAAACwAAAAABgASAAAIMAAVCBxIsKDBgwgTDkzAsKGAhxARSJx4oKJFAxgzFtjIkYDHjwNCigxAsiSAkygDAgA7) repetition-x bottommost}
I tin acknowledge that a greasemonkey book would privation to bundle thing it tin inside the origin arsenic opposed to adult it connected a server, that’s apparent adequate. However since I had not seen this method antecedently, I thought of its usage and it appears interesting for a figure of causes:
- It volition trim the magnitude of HTTP requests connected leaf burden, frankincense enhancing show
- If nary CDN, past it volition trim the magnitude of collection generated done cookies being dispatched alongside of photos
- CSS information tin beryllium cached
- CSS records-data tin beryllium GZIPPED
Contemplating that IE6 (for case) has issues with cache for inheritance pictures, this appears similar it’s not the worst thought…
Truthful, is this a bully oregon atrocious pattern, wherefore WOULDN’T you usage it and what instruments would you usage to base64 encode the photos?
