html - 根据复制量调整文本大小

Question

我目前在媒体查询中处理的一段代码有一个奇怪的行为。 我使用了相同的 div 类来设置出现在网站内不同页面的一段文本的样式，但文本显示的大小不同，具体取决于是否有 1 行、2 行或更多行文本。

有问题的 div 类是 .credits_mobile

HTML

<div id="project_content_mobile">
<div class="project_title_mobile">
Spaces
</div>
<div class="project_description_mobile">
A fashion editorial based around the quote ‘There is no difference between time and any of the three dimensions of space except that our consciousness moves along it’ H.G.Wells The Time Machine (p.374,2001.) Through the use of mirrors and reflections the aim was to create new spaces and perspectives that play with what the eye sees and takes influence from the cubist movement.
