I need to remove the two ticks that contain the x-axis line.. I was able to hide all of the inner ones with the CSS
.c3-axis .tick line {
display: none;
}
but this does not remove the two marks at either end on the x-axis line. How can I remove these?

@veronicaerick you mean the tick marked as red box?

If so, you can do setting option like:
c3.generate({
...
"axis":{
"x":{
tick: {
outer: false
}
},
});
@netil I used you solution but this just removes the tick from one end of the axis not on both the ends. Is there any option to remove the tick from the other end as well?
Thanks.
Edit: Also I wanted to remove the text below the tick (the scale values), how do we do that?
@veronicaerick, @netil solution working well 馃憤,
