Menu jumps when blog has been scrolled down

[simrandhamija]

Hi, I installed your theme and created a post. When I scroll down on the post and then expand the menu, the "back to top" and "next" button jump.

This happens only when I have a single post on the entire website. I created another post just to stop this behaviour. You can have a look at my blog here.

I tried to recreate this, but didn't experience any issues.
Is this the action your talking about?

[simrandhamija]

Hi. Yes, that is exactly the action this issue is about. This is what I am currently facing:

I have modified the source files a little. This is my config.yml for the theme cactus:

I can't reproduce this. I'll leave it open for a while and see if someone else encounters the same problem.

[thang-d]

I have met the same problem. I see my posts and I recognized that when my TOC is empty (don't use any heading # markdown in the post) the "back to top" and "next" button jumped. Besides although I'm in a top of the post, the navigator does not show for me. You can test it with a single post, do not have any heading or anything about TOC, it will show for you.

[probberechts]

Even when the TOC is empty, I can't reproduce this. Do you have any suggestions on how to fix this? Which browser do you use? Can you test it in a different browser? Also, make sure to disable all your plugins.

[thang-d]

Oh, I just tested on another computer with a post has TOC empty. Both are using Chrome browser (same version).

The computer has a larger screen (24 ins) it doesn't show any wrong but with a small screen (15 ins) the "back to top" and "next" button jumped when hovered to it. I tried remove onmouseover="$('#i-prev').toggle();" onmouseout="$('#i-prev').toggle();" of button prev in action_desktop.ejs, the menu didn't jump again when hovering to button prev. But when I tried to minimize browser on screen 24 ins, it's working ok, not jump. Do you have any idea in this case? Also, I make sure to disable all my plugins.
