Bootstrap 3.1 gradient less mixin error on IE8 and 9 -


i have problem gradient mixin ie8 , 9 browsers because gradient mixin seems have little bug because hexa code gradien has many characters resulted bootstrap mixin. if encountred problem , solved please share. less mixin bootstrap:

  .vertical(@start-color: #555; @end-color: #333; @start-percent: 0%; @end-percent: 100%) {     background-image: -webkit-linear-gradient(top, @start-color @start-percent, @end-color @end-percent);  // safari 5.1-6, chrome 10+     background-image: linear-gradient(to bottom, @start-color @start-percent, @end-color @end-percent); // standard, ie10, firefox 16+, opera 12.10+, safari 7+, chrome 26+     background-repeat: repeat-x;     filter: e(%("progid:dximagetransform.microsoft.gradient(startcolorstr='%d', endcolorstr='%d', gradienttype=0)",argb(@start-color),argb(@end-color))); // ie9 , down   }

variables:

@table-header1: rgba(155,214,45,0.65); @table-header2: rgba(123,192,67,0.99);

less: 

.table {   thead tr {      font-weight:normal;      #gradient > .vertical(@table-header1 , @table-header2);        th {         text-shadow: 0 1px 0 rgba(255, 255, 255, 0.9);         color: @asf-table-th-color;         border-color:#428bca;         border-width: 1px;         font-weight:bold;      }    } }

and result mixin:

  .table thead tr {       font-weight: normal;       background-image: -webkit-linear-gradient(top, rgba(155, 214, 45, 0.65) 0%, rgba(123, 192, 67, 0.99) 100%);       background-image: linear-gradient(to bottom, rgba(155, 214, 45, 0.65) 0%, rgba(123, 192, 67, 0.99) 100%);       background-repeat: repeat-x;       filter: progid:dximagetransform.microsoft.gradient(startcolorstr='#a69bd62d', endcolorstr='#fc7bc043', gradienttype=0);      }

now if hex code ie filter gradient has many characters.

this example of ie8 gradient correct hex code:

filter: progid:dximagetransform.microsoft.gradient( startcolorstr='#1e5799', endcolorstr='#7db9e8',gradienttype=0 );

your example of correct hex value wrong, can see @ http://msdn.microsoft.com/en-us/library/ms532930(v=vs.85).aspx startcolorstr should set to:

color expressed in #aarrggbb format, aa alpha hexadecimal value, rr red hexadecimal value, gg green hexadecimal value, , bb blue hexadecimal value. alpha value controls opacity of object. alpha value of 00 transparent, while value of ff opaque. string input outside hexadecimal range revert default value (#ff0000ff).
