Mobile View of Mathematical Expressions - Grey mathematical expressions on grey background

very simple mathematical expression in mobile view of article not visible in all browsers. Seems to be a issue of CSS alterations.

• Checked for other pages https://en.m.wikiversity.org/wiki/COVID-19/Mathematical_Modelling/Exponential_Growth to see if it just a problem for OpenSource article.

The CSS alteration for mobile view results in "Light grey background" for light grey mathematical expressions. Same is true for other pages in the english Wikiversity.

• Checked corresponding page in german wikiversity https://de.m.wikiversity.org/wiki/COVID-19/Mathematische_Modellierung/Exponentielles_Wachstum if the same CSS alteration are performed there as well. (German Wikiversity Math Expression OK) The layout is rendering in mobile view properly as before as before.

Maybe reverting the CSS alteration on the english wikiversity could fix the problem with the mobile view of mathematical expression easily. Checked with a simple expression like a+b to be sure that is not a rendering problem of complex mathematical expression.

@Bert Niehaus: I've tried three different browsers. I'm not seeing any issues. Try clearing your browser cache or use a different browser to see if the problem continues. -- Dave Braunschweig (discuss • contribs) 13:54, 4 September 2021 (UTC)

@Dave Braunschweig: Seems to be fixed now. Was a "fresh" operating system at my end. Next time I will do more in depth tests on different operating systems and the major browsers to trace down the problem a bit better. Using the same background colour as the colour of text/math expression (here light grey) hides the text/formula (that is not standard to hide DOM elements, and as far as I could reconstruct that, the CSS settings was assigned to the tag <math>.

Thanks for cross checking the problem, Dave. --Bert Niehaus (discuss • contribs) 13:42, 5 September 2021 (UTC)
