Some beamer color themes (as seagull) define alert text as bold font.
However, sold font alerts are annoying when one uses overlay (eg: \onslide+<2->
), because bold text takes more space than normal text, which breaks the illusion of an animation.
To change alert from normal to bold, we can use the command
\setbeamerfont{alerted text}{series=\bfseries}
(see here). Unfortunately, I was unable to revert this by using something like
\setbeamerfont{alerted text}{series=\normaltext}
I don't know if this is because this command is wrong or if it is because it can't override seagull's settings.
Does someone know a trick to set non-bold text with the \alert
command while using seagull color theme?
\setbeamerfont{alerted text}{series=\mdseries}
or\setbeamerfont{alerted text}{series=\normalfont}
