In Firefox, two elements sharing the same class appear to have distinct appearances

I am encountering an issue with two <hr> elements that have the same class but display differently in Firefox compared to Chrome. Oddly, the bottom one appears normal while the top one is double the thickness it should be.

Does anyone have any suggestions on how to resolve this problem? I'm also open to alternative methods for creating a 2.5px high black line.

The problem can be seen on every page of my website . In Firefox, the black line at the top appears too thick, while the one at the bottom looks fine. All other browsers display both lines correctly.

Answer №1

Consider incorporating height: 2px; instead of 2.5px;

If you desire to specify values in decimal fractions, consider using 2.5em instead. Decimals are suitable for em units but not for pixels.
