Live search alignment

Hello,

I have installed relevanssi to enhance search, the live search bar appearing below the search bar when typing is misaligned. I tried with the plugin author ways to resolve this , the best shot I got is:

#rlvlive_2 {
    left: -950px;
    position: relative;
    top: -65px;
}

I have tried different px values but nothing seems to work on all screen sizes/devices.
The issue of misalignment remains depending on what monitor size you use or when the browser window is reduced.

I wanted to know, at a theme level is there any way to integrate this in a responsive way so that the alignment remains regardless on the above parameters.
