When I use the mobile version, I want the line spacing of the text in my article

Hi Miles,

Are you referring to the line-height?

If so, you can set different line-height for mobile at customizer > typography > body.

I should adjust the letter spacing, but I have already tried to adjust it according to what you said. However, the actual situation is that it shows correctly when I adjust it in the backend, but when I view it on another mobile phone, there is no change, even though I have cleared the cache. However, the desktop version of my page can be adjusted normally.

Have you tried clearing the browser cache of your mobile phone?

It sounds like a cache issue.

If that doesn't work, can you link us to your site so we can inspect the code.

It seems that this is not a caching issue because when I make other changes, the phone can update immediately.

Hi there,

on your site i see this on desktop:

font-size: 19px;
letter-spacing: 0.59px;

and this on mobile:

font-size: 20px;
letter-spacing: 2.07px;

So it is working but the noticeable spacing difference for that character set is pretty minimal.

I followed the steps you provided to adjust the font size to 6px font in the field for mobile adjustments, but there was no change in the display on my phone, even though I cleared the cache repeatedly.

I also tried to adjust the font size display for H2, but encountered the same problem. Although I could see the changes when adjusting in the backend, there was no actual change on my phone. The only way I can make adjustments is through the editor in the article, which is quite troublesome.

Hi Miles,

For reference, can you share screenshots of the issue from your end?
