Here is the HTML code:
div {font-size:1.5em}
div b {font-size:2em}
div {width:360px; border:1px solid red}
<div><b>“</b>The real test is not whether you avoid this failure, because you won't. It's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere.<b>„</b></div>
<div><b>“</b> The quick brown fox jumps over the lazy dog...
The quick brown fox jumps over the lazy dog...
The quick brown fox jumps over the lazy dog..
The quick brown fox jumps over the lazy dog.
The quick brown fox jumps over the lazy dog..
The quick brown fox jumps over the lazy dog.
<b>„</b></div>
The last line will have a higher height which looks quite weird.
Is there any way to fix this?
