26px +  4px (border width) = 30px which is half the height of the 60px circle.

Thanks a million for the assistance, Tom. I doubt that I would ever have 
figured that out. It's not exactly intuitive that
specifying a 'border radius' for a square object is the way to specify a circle.
 
I must confess that I haven't yet figured out why a margin of 26px is called 
for. It obviously is, of course.
 
Thanks again    Bruce

In keeping with "primitive":


.wrap{position: relative;width: 500px;}
.circle1 { border: 4px solid #99;
height: 60px; width: 60px; border-radius: 60px; margin: 26px
auto 0 auto; }

.circle2 { border: 4px solid #99;
height: 120px; width: 120px; border-radius: 120px; margin: 0
auto 0 auto; }



 


I would guess SVG might be better, but I am not familiar with it.

After a quick test, it's not as smooth as borders (in FF). Though that
may be fixable with different settings. Like I said, it was a quick

Also, may be able to do it with a radial gradient and some
well-planned color stops, but you may be then excluding some browsers
you need to support.

[css-d] Simple display of concentric circles

2014-01-21 Thread bruce . somers
I've got some sort of mental block. I would like to display a series of 
concentric circles with diameter 2 cm, 4 cm, 6 cm, 8 cm ...
 
At the moment, I have
.circle1 { border: 4px solid #99;
  height: 60px; width: 60px; border-radius: 60px; }
  
.circle2 { border: 4px solid #99;
  height: 120px; width: 120px; border-radius: 120px; }
 
 
 
 
 
You're right - it IS quite primitive. I would like to be able to write

 
and have all the circles drawn with a common center.
 
Can it be done with CSS?
