QS:Time limit timer style
From LimeSurvey Manual
Time limit timer CSS style (time_limit_timer_style)
Description
It allows (and overrides the default) css styling used to display the countdown timer. The default style value for this attribute will be used if it does not exist, which is: 'width: 150px; margin-left: auto; margin-right: auto; border: 1px solid #111; text-align: center; background-color: #EEE; margin-bottom: 5px; font-size: 8pt;'.
Any text entered into this attribute will overwrite the entire default css style, so you should ensure that care is taken when entering a value for this attribute. A simple way to hide this is to copy the default style into this attribute and add 'display: none;' to the end.
This settings is only applicable if the general time limit setting is activated.
