私のテキスト区切りには透明な黒の背景色が必要です。しかし、divの背景色を黒に設定すると、小さな帯だけが覆われます。また、私はそれを透明にすることはできません（少し灰色がかっています）。背景色はテキスト区切りをカバーしません
これは私のコードです：

<div class="info">Reggae has been at the forefront in the development of music for many years now.
From Electronic Dance Music to Pop to Punk to Disco and several other music genres today, you can hear the influence
of Reggae coming from their core. One genre of music in particular that is directly influenced from Reggae is Hip-Hop.
Those familiar with Hip-Hop’s history know that the culture was started in the late 70’s in the Bronx, NYC. The founding
fathers of the culture are Afrika Bambatta, Grandmaster Flash and DJ Kool Herc. DJ Kool Herc being a native of Kingston,
Jamaica always credits his Jamaican roots for his early techniques and development of the culture.
<br>
<br>
Reggae music’s traditions of dubbing out tracks and toasting on the microphone are a direct lead in to hip-hop’s sampling &
emceeing (now known as rapping). In Jamaica, dubbing out a track was the same as making a instrumental remix of a original song.
It would usually be the B-side of a Jamaican 7″ single with the original song being the A-side. It involves stripping away most
of the instrumentation of the song, vocals and melody highlighting the heavy drums and bass line. This would allow for a artist
to “toast” or chat live on top the beat in the same way a Hip-Hop emcee can freestyle over the instrumental of their favorite
track. And well known Jamaican Dub architect Lee Scratch Perry created the idea of putting sound effects such as babies crying,
gunshots, breaking glass, etc. into his dubs and tracks thus inventing sampling. So as you see, elements of Hip-Hop can be traced
back to techniques that came from Jamaican studios years earlier.</div>
