Change Javascript Dynamically with Screen Width & Height for Responsiveness

I am using wordpress revolution slider with tabs under slider.

As these tabs are looks good on large resolution but not looks good on mobile and iPad. So I want to make it responsive for all devices.

Now I find out that this slider tabs width generate dynamically from Javascript.

This is tabs which need to be responsive.

I am not sure which attribute will make it responsive.

Please give some suggestion on it,

Thanks.

Javascript Code

<script type="text/javascript">var htmlDiv = document.getElementById("rs-plugin-settings-inline-css"); var htmlDivCss="";
                        if(htmlDiv) {
                            htmlDiv.innerHTML = htmlDiv.innerHTML + htmlDivCss;
                        }else{
