Sir i just want that the description of the product in the mobile theme is to drop down by the user but i want it to let it open so that it can be easily read by the users.
So sir how can we do it.

In responsive.css located in css folder in theme,
bellow line:
@media screen and (max-width: 767px)

find:
#more-info .item-description

and put there:
display:block;

Sir i have tried this but the display is still like this.

Sir i have put up your code in the site but it has changed the full view of the site but i want only the description part to show as block or be opened before not the drop down in the site so how can i do that.

Code I sent you is not correct, must check it

Sir i have put the code then only the responsiveness of the website got changed fully. But i want the description part to be opened or visible without drop down.

Sir please rply on this topic.

in this image where should i put.
display:block;

First read css basics if you want to modify something.

Sir i want the seller info and listing location part to display as block same as the discription part.

We gave you guide to description already, you can use same pattern for other fields. If you have insufficient skills to do it, it's better to hire developer to do modfications for you.

Sir it is not about the skills its about finding the correct words or line in which we have to put {display:block;} So please help to implement it as the theme is being developed by you and your team.

Sir can u please rply for it.

@Satbeer
All you need to know is there. If you expect someone will tell you "what file", "what line", "what code", then you will fail, noone will do this nowadays, it's time and money saving for you to hire developer for such work.
