Remove list bullets

For anyone who would need that, here’s how I did :

I used the Google Chrome Developper Tools to search the class/id of the attribute. In my case, it was li.ca_cepage.

.summary li.pa_cepage {
    list-style-type: none;
    margin-left: -50px; /* To remove the blank space */
}

As I had to remove the blank space using a negative margin-left, I targeted the attribute in the .summary so it doesn’t display wrong in the Shop page with all the products.

Then, I wanted to make the attribute title bold, here’s how I did:

.summary .attribute-label {
    font-weight: bold;
}

I hope it helps!
