初歩的な質問で申し訳ございません。

画像URLを入れるまではわかりました。


１、下記HTMLは全部入れるのでしょうか？
２、(《画像URL》)はどこまで残すのでしょうか？（URL）ですか？
/* お気に入り商品登録画像変更 */←これは消さなくても良いですか？
３、入れても表記しないのはプレビューだからですね？
４、下記のような場合どの場所に入れたらよいでしょうか？レフトﾅﾋﾞ有り無しと２パターン使っています。


<style>
/* お気に入り商品登録画像変更 */
body #rakutenLimitedId_aroundCart div.bkm{
width: 306px !important;
}
body div.bookmarkArea div.bkm a.addBkm span.bkmStar {
width: 306px !important;
height: 48px !important;
background: url(《画像URL》) no-repeat 0 0 !important;
}
body div.bookmarkArea div.bkm a.addBkm {
width: 306px !important;
height: 48px !important;
}

/* お気に入りショップ登録画像変更 */
body #rakutenLimitedId_aroundCart div.shopBkm{
width: 306px !important;
padding-left: 0px !important;
}
body div.shopBookmarkArea div.shopBkm a.addShopBkm span.shopBkmStar {
width: 306px !important;
height: 48px !important;
background: url(《画像URL》) no-repeat 0 0 !important;
}
body div.shopBookmarkArea div.shopBkm a.addShopBkm {
width: 306px !important;
height: 48px !important;
}
</style>
