How to add padding to reviews

No, you could add it to the Simple CSS area in Appearance > Simple CSS and it will apply globally.

If you need help with the CSS, feel free to link me to the page :)

yes this is the page https://wildlatina.co/product/cindy/

whats the css code for adding padding to the reviews section on the bottom, and is there some way to disable the avator/profile icon thats on the right side for each review? and the stars inside the reviews, they are on the right side, how to put them on the left side above the name of the reviewer? and disable or remove that white border line around the reviews.

If you set the Page Builder Container meta box to default, padding will be added by default.

Otherwise you can do this:

#reviews {
    padding: 40px;
}

For the avatar, try this:

#reviews .comment_container img {
    display: none;
}

For the reviews, do this:

#reviews .meta {
    clear: both;
}
