1. border-radius:35px; will yield rounded border for all sides
2. border-radius-topleft:35px; will yield rounded border at the Top left side and note that the type is "px" pixel.
3. border-radius-bottomright:35em; will yield rounded border at the Bottom Right and note that the type is em where 1em = 16pt "pt" is points
4. border-radius:35px 0px 35px 0px; will yield rounded borders at topleft and bottom right postitions. the general syntax is
   border-radius:topleft topright bottomright bottomleft;
   It can be in any type.
5. When you don't mention border-radius property, there will be no rounds, but there will be square borders

Browser Specific Definitions - CSS

Read : How to define CSS in General HTML and Blogger and as tag?

Lets take the following example,

.textborder{-moz-border-radius:0.5px}

In the above code, I've mentioned something -moz- before border attribute. Why?
All browsers doesn't support basic codes. Each browser has their own attribute definition.

Attribute to be added	Browser	Example
-moz-	Mozilla	-moz-border-radius:0.5px;
-o-	Opera	-o-border-radius:0.5px;
-ms-	Internet Explorer	-ms-border-radius:0.5px;
-webkit-	Safari & Google Chrome	-webkit-border-radius:0.5px;

So? What If my webpage will be viewed in all of these browsers? How will I define  for all browsers?
Yes! You can define for all browsers. You should define the CSS as follows,

.textborder{
border:0.5px solid black;
-moz-border-radius:0.5px;
-o-border-radius:0.5px;
-ms-border-radius:0.5px;
-webkit-border-radius:0.5px;
border-radius:0.5px;
}

I have mentioned border-radius at the end. Why?
When we've left any of the browser in browser specific definition, the one without browser specific definition may take effect.

Now, the CSS result can be viewed in all browsers as below.

CSS as tag.

Read : How to define CSS in General HTML & in Blogger.

Removing a dot while defining CSS will help you to use CSS style as tag.
For example :
We defined CSS with a prefixed dot as,

.textborder{border:0.5px solid black}

and used as,

<div class="textborder">Something here</div>

Now, we will define the CSS in the same way, but without a dot as

textborder{border:0.5px solid black}

and use as,

<textborder>Something here</textborder>

The result will be as follows :-
Something here and when your text expands, the border will expand
And, when you come to next line, It will look like this. Border for each line.
