<p class="leading-none ...">So I started to walk into the water...</p>
<p class="leading-relaxed ...">So I started to walk into the water...</p>
<p class="leading-3xl ...">So I started to walk into the water...</p>Fixed line-heights 
Use utilities like leading-3 and leading-10 to give an element a fixed line-height, irrespective of the current font-size. These are useful when you need very precise control over an element’s final size.
