Hi I have read the docs and it mentions that st.slider ‘label’ can include ‘inline code’.
I have tried this:
st.slider(f'''<p class="res">{col}</p>''', min_value = float(min_val), max_value = float(max_val), value = float(val))
This adds the label to a stMarkdownContainer div, however it copies the inline code instead of passing it.
The labels accept a subset of Markdown, which doesn’t include raw HTML unfortunately. So if you want to make the label bold, you could have
st.slider(f'**{col}**', min_value = float(min_val), max_value = float(max_val), value = float(val))
If you are looking for something more elaborate, you would have to inject some CSS to grab the element by other means.
Just to clarify: by ‘inline code’ we mean the <code> HTML element:
Thank you so much for your answer, it would be nice to be able to add a CSS class to any element.
For now I will stick with bold 
Thank you, although I cant think of may reasons you would want to dispay a code snippet as a slider label
