How to replace slider in WP site?

Question

WordPress

There is a site on WordPress. An order was given to replace this slider with another one (slider dimensions are the same). The question is, how do I replace it? I have already written my slider, now I need to somehow change the old one to mine. I think that either I will edit the html and css code of the site, or I will add a slider to the main page using WP. If you have to edit the site code, then how can I do it, because I practically did not work with WP. Maybe in WP you can somehow open the site code and rewrite the old slider there with the new one?

Answer 1

Template files can be picked through the tabs "Appearance => Edit".
But to save the result, you need to do this on a child theme (otherwise, when updating, all changes will fly off, at best).
Another option is through this or a similar plugin (html embedding is also there), but there will be much more fuss with CSS.
