Blogスクープはなかなか便利なものです。
引用した文章を枠をつけたいと思って、いろいろいじってみましたが、いずれも失敗しました。
何となく、検索していたら以下のBlogにヒット。
cssに付け加えたら、簡単に出来ちゃいました。
こもぞうのひとりごと
引用は四角の枠で囲むようにしました
他の人のBlogを見てたら引用部分がわかりやすく装飾されているのがあった
どうやるんだろうと思って、googleで『css 引用』で調べてみたら『超簡単!CSS講座(引用の囲み方)』を発見さっそくスタイルシートに
blockquote {
margin-right: 2em;
margin-left: 2em;
padding-left: 1em;
border: dashed 2px #FFCC66;
width: auto;
color: #000080;
}
を加えてみました

感謝感激です。ありがとうございました。
今日現在のほっとメール@ひたちのcssです。ご参考までに。
