InDesign文字組みアキ量設定をCSS text-spacing-trimプロパティで

InDesign文字組みアキ量設定に対応するCSSのプロパティ指定

はじめに:CSS text-spacing-trim プロパティが利用可能に!

CSS Text Module Level 4text-spacing-trim プロパティ が最近のブラウザ Chrome (Chromium) 123 以降で利用可能になりました。また、CSS組版ソフトVivliostyleでも以前から利用可能です。

この text-spacing-trim プロパティの機能(行頭・行末や連続する約物の詰めの制御)は、DTPソフトのInDesignの文字組みアキ量設定に近いものです。そこで文字組みアキ量設定に対応するCSSでの設定方法をまとめます。

text-spacing-trim プロパティの値は次の通り:

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
