In addition to the element I.D. and class elector there are a number of other selectors that jury supports
will go through a few in this lesson for a more comprehensive list check the file in the downloads folder
corresponding to this lecture we can apply in action to all the elements in an HCM l document using
the asterisk
if we save the file and preview this in our web browser
you'll notice I when we clicked the hide button it hides all the elements
we can also apply in action to the current HDMI out element by using the this selector and in this case
the current element would be the button itself
so if we refresh the web browser and click hide the hide button disappears
we can select all button elements using the button selector
and if we could hide again the button disappears so as you can see changing the selector is fairly easy
and there's many different options so do check the file in the downloads folder for a more comprehensive
list.
