Mastodon(v1.4.4)を白くする追加CSS

by 7_nana

Mastodonのデフォルトのデザインはダークカラーが基調となっている。深みのある色の上に白文字があると目にとても優しい。しかしインスタンスのテーマによっては、このトーンが合わない場合があるかもしれない。色はその場所のムードを表す。なのでMastodonを白くしてみた。

Mastodonの色を変えたい時、1番簡単な方法は「mastodon のテーマカラーの変更は簡単だよ - Qiita」に書かれている。ただこの方法だとダークトーンは問題ないが、白くしようとするとあちこちで問題が出た。そのため、application.css の末尾にCSSを追加して上書きする方法を取った。

このCSSについて

注意点

Mastodonを白くする「おしろいCSS」

読みやすいように改行・コメント・スペースを入れているが、実際は全て取り払い application.css の末尾に追加してCSSを上書きする。カスタマイズしやすいようにプロパティ基準+複数セレクタで整形。

反映方法

私は「Mastodonのカスタム方法 | みんなのメモ帳」を参考に /public/packs/ の中の application.css に追記して上書きアップロードしている(記事にも書かれているが、これはあまり推奨されない方法だとは思う)。

反映後のユーザーさんの反応

一度、試験的にMastodonを白くした2日後、バージョンアップで再び黒に戻った。その際に白UIが良いか黒UIが良いか改めてユーザーさんにアンケートを取ったところ、白UIの票が多かったので採用することにした。票を入れてくださった方々は、割とすぐ白UIに慣れたようだった。

更にカスタマイズするなら

サイト名とカラムヘッダーに使っている紫(#800080)をインスタンスのテーマに合う色に変更すると、手っ取り早く良い感じにできると思う。また、白以外のスタイルにも変更しやすいと思うので、興味のある方は使ってみてください。
