d3.js - CSS override isn't working (d3 object) -

-

i'm trying apply learned in css foundation course (codeschool) style d3 objects , far i'm not getting right.

i have bunch of css classes style charts. have 2 types of charts, second type need override 1 color.

main css (i didn't create myself)

.horizon {   border-bottom: solid 1px #000;   overflow: hidden;   position: relative; }  .horizon {   border-top: solid 1px #000;   border-bottom: solid 1px #000; }  .horizon + .horizon {   border-top: none; }  .horizon canvas {   display: block; }  .horizon .title, .horizon .value {   bottom: 0;   line-height: 30px;   margin: 0 6px;   position: absolute;   text-shadow: 0 1px 0 rgba(255,255,255,.5);   white-space: nowrap; }  .horizon .title {   left: 0; }  .horizon .value {   right: 0; }

override css (for second type needed different color) (this used first file changing horizons horizon_small bad know.)

.horizon .horizon_small {   border-top: solid 1px #bdbdbd;   border-bottom: solid 1px #bdbdbd; }

applying here:

 d3.select("#mychart")    .selectall(".horizon")    .data(data).enter().insert("div", ".bottom")    .attr("class", ["horizon", "horizon_small"]) // used "horizon_small"

but doesn't work, not sure problem is.

the selector ".horizon .horizon_small" targets element class "horizon_small" inside (at level) other element class "horizon". if want target elements both classes, selector should ".horizon.horizon_small".
