content modules - carousel problem

That comes from your template's CSS.

You have that CSS in your template:
ul ul {
margin-left: 25px;
padding: 5px 0;
}

That forces the margin of the uls of the carousel and makes it go on two lines.
Either remove it from your template's CSS, or override it like with some additional CSS:
ul ul {
margin-left: 0px !important;
}

And that will solve the problem.

No. The CSS is compressed by your template. So it's impossible to know from which file that comes.

However, you could add the override code in the front end CSS of HikaShop via the Display tab of the configuration.
That should work too.

Hi,

You can just click on the edit button of the front end CSS option. There is no need to change the selection.
You can add your CSS at the beginning or at the end of the file.
