xml - Rotating SVG CSS Animation in Firefox Not Working, and Need SVG Fallbacks -


i'm trying animate these gears, , works intended in chrome. however, in firefox rotation origin different, , can't figure out how fix this.

i've tried playing width, height, viewbox, , x & y attributes, nothing seems work perfectly.

based on svg rotate path example.

and finally, best practice providing proper fallbacks svg paths in other/older browsers not support graphic/animation?

the rest of code here: jsfiddle here (html + svg code long paste)

css:

#gear-head {   position: fixed;   background: #172235;   width: auto;   height: 100%; } #gear-head .gear {   -webkit-animation: rotation 6s infinite linear;   -moz-animation: rotation 6s infinite linear;   -o-animation: rotation 6s infinite linear;   animation: rotation 6s infinite linear;   transform-origin: 50% 50%;   -webkit-transform-origin: 50% 50%;   -moz-transform-origin: 50% 50%; } @-webkit-keyframes rotation {   {     -webkit-transform: rotate(0deg);   }   {     -webkit-transform: rotate(359deg);   } } @-moz-keyframes rotation {   {     -moz-transform: rotate(0deg);   }   {     -moz-transform: rotate(359deg);   } } @-o-keyframes rotation {   {     -o-transform: rotate(0deg);   }   {     -o-transform: rotate(359deg);   } } @keyframes rotation {   {     transform: rotate(0deg);   }   {     transform: rotate(359deg);   } } #gear-head .pulsating {   -webkit-animation: pulsate 6s ease-out;   -webkit-animation-iteration-count: infinite;   opacity: 0.5;   transform-origin: 50% 50%;   -webkit-transform-origin: 50% 50%;   -moz-transform-origin: 50% 50%; } @-webkit-keyframes pulsate {   0% {     -webkit-transform: scale(0.5, 0.5);     opacity: 0.0;   }   50% {     opacity: 1.0;   }   100% {     -webkit-transform: scale(1.2, 1.2);     opacity: 0.0;   } }

the simple solution use half-height , half-width units:

instead of transform-origin: 50% 50%;

get width , height of svg (ex: width="234px" height="186px"); divide both values 2 (to 117px , 93px, respectively); use

transform-origin: 117px 93px;

this should work on browsers (i tested on safari, chrome, , firefox)

css - SVG using textPath a symbol not rendering in Firefox -

using textpath within symbol doesn't render in firefox. renders fine in latest chrome , ie, when try reference symbol, svg text doesn't render in firefox (37.0.1) - first box appears empty. code below (no external dependencies), there should 2 boxes word test flowing vertically in centre of each. edit: thought issue somehow involved flexbox layout, until paul pointed out issue exists without flexbox layout. the html is: <div> <svg id="not_working" viewbox="0 0 250 1200" preserveaspectratio="xmidymid meet"> <symbol id="test_symbol1" preserveaspectratio="xmidymid meet" viewbox="0 0 250 1200"> <path id="test_symbol_path" d="m 100 1200 l 100 0" /> <text font-size="100" fill="red"> <textpath text-anchor="middle" startoffset="50%" xlink:href="#test_symbol_path...

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
