Rounded corner only on one side of svg <rect> - html

Question

I am trying to implement a bar chart like diagram. I have the following html element
<rect x="35" y="-135" width="10" height="51" style="stroke: rgb(255, 255, 255); opacity: 0.8; fill: rgb(255, 122, 0);"></rect>
I want to give the top corner of the rectangle a rounded shape.
How is it possible?
I am not able to apply border-radius property.

Answer 1

You may use clipPath too. It's kind of a hack but it may be easier to implement.
Assuming the follow:
your rect is width="10" and height="51"
the top corner will be rx="5" and ry="5"
<svg>
<defs>
<clipPath id="round-corner">
<rect x="0" y="0" width="10" height="56" rx="5" ry="5"/>
</clipPath>
</defs>
<!-- if you want to use x="35" y="-135" put clip-path on a `g` element -->
<rect width="10"
height="51"
clip-path="url(#round-corner)"
style="stroke: rgb(255, 255, 255); opacity: 0.8; fill: rgb(255, 122, 0);"></rect>
</svg>
Some Notes:
So the clipPath > rect > width is exactly the same as your rect.
Instead for clipPath > rect > height, you have to consider the corner radius on top and thus the height should be rect.height + desired-corner-radius (in this case 51px + 5px).
In that way you won't touch the bottom part of your rect with the clipPath.

Answer 3

As commented by Robert Longson you need to convert your rect element to a path element to control the rounded corners.
In the following example, I used a cubic bezier curve with the Q command to make the top left rounded corner (Q1 1 5 1 in the d attribute):
svg{
height:90vh;
width:auto;
}
<svg viewbox="0 0 10 50">
<path d="M1 49 V5 Q1 1 5 1 H9 V49z"
fill="rgba(255, 122, 0, 0.8)" />
</svg>

Use the <path> element with the arc command (http://devdocs.io/svg/attribute/d#arcto).
Syntax: a rx,ry x-axis-rotation large-arc-flag sweep-flag dx,dy
<svg width="200" height="200" viewBox="0 0 10 10">
<path d="M0,8 v-3 a5,5 0 0 1 5,-5 h3 v8 z" />
</svg>
