box shifts down if break is used

[s_avinash_s]

Hi 

By using below style i can able to create two boxes which are side by side

#rcorners3 {
    border-radius: 25px;
    border: 4px solid #92a8d1;
    padding: 20px; 
    width: 755px;
    height: 150px;    
}

If i keep  <br> or my text exceeds the box size , the other box shifts down.

But i need to use <br> inmy code.

How to proceed ,Please suggest
