はてなブログの記事下に SNS で投稿するボタンを独自に追加する
執筆日時:
ちょっと長いけど、はてなブログの[デザイン設定]-[カスタマイズ]-[記事上下のカスタマイズ]-[記事下]に張り付けるだけで使える。グレースケールで目立たないデザインだけど、マウスホバーで色付きになるぜー(ぃぇーぃ
あと、はてなブログって標準で jQuery を使ってるのかな? だったらこの行は消した方がいいかもしれない(ローカルでテストするために使っていた)。

開発は Visual Studio Code + ASP.NET Core で行いました(なんとなく)。

最初は Ligature Symbols という Web フォントを使って組んでいたのだけど、クロスドメインで読み込めなかったので(ローカルサーバーでは動いたのに……orz)、SVG を拝借して書き直しました。なので、いろいろ残骸が残ってて、微妙に無駄の多い感じになってる気もするけど、まぁ、とりあえず動いたのでいいかな、みたいな。
参考
SVG のアイコンは、ここからいただいた。ぜひ Pocket のも作ってほしいなー。
共有数をカウントするコートはここから拝借した(Facebook が動かなかったんだけど、typo があるみたい。Chrome デベロッパーツールがなかったら見つけられなかったゼ……)。Twitter と Google+ はめんどいので割愛。
