I’m so sorry, JA Rasite Template does not support responsive layouts.
If you would like to make responsive layout on this template, you can look at my for example as below
Open templates/ja_rasite/css/template.css file
Add script
/* mobile*/
<blockquote>@media (max-width: 767px) {
body#bd .main {
width: 100%;
}
}</blockquote>
You can appear to do that with tablet and mobile layout
/* tablet */
<blockquote>@media(min-width: 768px) and (max-width: 979px) {
// css class
}
</blockquote>
/* fullsize*/
<blockquote>@media (min-width: 1200px) {
// css class
}</blockquote>
