I am trying to use these icons along with openweathermap and i successfully managed to, although i can not change their size! They way they are used is like font-awesome ones : <i class="wi wi-omw-100"></i>
What attribute do i change to make it larger ? (font awesome ones don't work i tried!) and i couldn't find something specific in the documentation.
