Here is a base HTML markup for your timer/stopwatch. Main part of HTML are data
attributes for render numbers of years
, days
, hours
, minutes
, seconds
. Every data
attribute isn't mandatory, TimezZ will recalculate time to smaller numbers.
For example:
- if you don't have years, a timer will add these years to days
- if you don't have days, a timer will add these days to hours
- and so on
<div class="timer">
Years: <div data-years></div>
Days: <div data-days></div>
Hours: <div data-hours></div>
Minutes: <div data-minutes></div>
Seconds: <div data-seconds></div>
</div>
