Hard-to-read capitalisation of type hints in class attributes

[jakelishman]

There's a CSS rule causing type hints that appear in the documentation of class attributes (such as those created by @dataclasses.dataclass) to be all upper-cased. I'm not certain which exact objects this is intending to capitalise, but type-hints should probably be exempt, since they're Python objects that are case-sensitive if people want to look them up / import them.

For example, on this page for an algorithms dataclass, the attributes are given all in uppercase. The Sphinx-generated HTML for a single attribute is (linebreaks inserted):

<dt class="sig sig-object py" id="qiskit.algorithms.optimizers.OptimizerState.x">
<span class="sig-name descname"><span class="pre">x</span></span>
<em class="property">
  <span class="p"><span class="pre">:</span></span>
  <span class="w"> </span>
  <span class="pre">Union</span>
  <span class="p"><span class="pre">[</span></span>
  <span class="pre">float</span>
  <span class="p"><span class="pre">,</span></span>
  <span class="w"> </span>
  <span class="pre">numpy.ndarray</span>
  <span class="p"><span class="pre">]</span></span>
</em>
<a class="headerlink" href="#qiskit.algorithms.optimizers.OptimizerState.x" title="Permalink to this definition">¶</a>
</dt>
<dd><p>Current optimization parameters.</p></dd>

(so Union, Optional etc are correctly cased in the HTML). The causing CSS rule seems to be:

article.pytorch-article .class em.property {
	text-transform: uppercase;
	font-style: normal;
	color: var(--purple);
	font-size: 1rem;
	letter-spacing: 0;
	padding-right: 0.75rem;
}

I don't know if it's more appropriate to remove the uppercasing entirely (I don't know what it's supposed to be uppercasing) or to change the selector of the rule so it isn't affecting these type hints.

The property you mention here is also responsible for capitalising the class title at the top of the page, so probably can't remove it completely, I'll have a look at some of the other css attributes around and see what makes the most sense
