how to apply line break <br> in href tag

with this i can achieve the required output is there any other way also? since in the div i am using it flows down far beyond (ex displayed ) expected may be need to change the div or somewhere since the screen design is complex i am searching for another workaround?

hello





world

I need to see it in context to understand what you mean.  You can add more <br> tags

No what i mean to say is when i apply the <br> tag the link looks like thsi
hello



world

but the expected output i need is
hello
world


there may be the issue of div in which it is wrapped or other way round,since there are a lots of css are used and screen design is quite complex,i need to know is there any workaround other than applying the
<a href ="hello_world">hello<br>world</a> to achieve the output

All we are going to get here is speculation until you post a link so we can see context.  An answer might  come from a lucky guess, and guessing is about all you are going to get with the information you have provided.

if i put this code in a plain html the output is
<a href ="hello_world" style="line-height:1em;">hello<br/>world</a>

hello </br> world

Is this exactly what you get
hello </br> world

If it is then you are not telling us the whole story.

this was exactly as per my requirement
