Hi midhat
1- For the icon in login module, if you inspect element via your web browser, you can see that icons are overridden by the style of eshop component. You should contact its provider for help to resolve this first.
2- You can use this custom css:
.com-content-article.item-page {
padding-left: 20px;
padding-right: 20px;
}
and change to your desired value.
