Nice tool!

Love to use it.

emmetを利用できるプラグインで最も優れています

テーマエディター上でemmetを利用したい目的から導入しました。emmetの利用はもちろん、豊富なオプションでカスタマイズ性も素晴らしいです。設定のUIも大変わかりやすいです。最終的に導入に至らなかった点は、テーマエディター上でファイル更新を行うと、ページが更新され元に戻せない点です。ページ更新やphpのエラーメッセージ表示・位置などがデフォルトの仕様であれば是非導入したいと思います。

It works perfectly !!!

I hope the developer continues to update it to avoid compatibility issues with future versions of WordPress.

Really impressed

Used with a block-based theme and it worked perfectly. Love that there is no configuration required and it auto-detects <code> and <pre> tags. Great plugin, thank you! This topic was modified
