/*
サイト上の構成の大枠としてページ内に1度しか出てこないものと、グリッドレイアウトについてを記述します。
We will write about thing the only comes out once on the page as a frame and grid(column) layout.

接頭辞はLayoutの頭文字を取って【l_】とします。
Prefix will take the "Layout" first letter and use it as "l_".

ここで指定するのは以下の様なものと予想されます。
You might use the following.
.l_wrap/.l_container/.l_header/
.l_nav/.l_main/.l_contents/.l_footer

モディファイヤを使用する場合は接頭辞【has_】をつけ、各レイアウトの下に記述します。
When using modifier put the prefix "has_" and write it under each layout.

フォントサイズはremで指定します。
"rem" will be used for font-size.
