lotlog on "[Theme: Isola] Empty space below menu button"

Hi there,
I'm using the Isola theme. While I tend to click the menu button, there is a empty transparent space under the menu button.
While I check the code, it's like below
<span class="screen-reader-text">Primary Menu</span>

Then I try to hide it with child theme.

.screen-reader-text { display: none;
}
.screen-reader-text:focus { display: none;
}

But it doesn't work.

1. What's this for?
2. How can I hide it?

Hey there,

Please post a link to your site. Thanks!

Hi there!

I was able to replicate on my own installation of Isola and have created a screenshot. Can you take a look and confirm if the highlighted area is what you were referring to?

I've reported back to the team behind this theme, also, and will let you know what I hear from them.

Hi Siobhan,
That's exactly what I met.
I tried to fix it on child theme. But it made no difference.
And I searched a lot, it seems related to something called 'screen-text' feature for visual impairment people.
Since you've already reported it back, I will wait for the reply.

Thanks.
