before we get into making a preloader which is what we see here let's first
talk about the most important thing should you use a pre loading screen of
any type some people say yes others say never
the answer is it's up to you page loads can go pretty fast
your preloader might look ridiculous if it's only up for a quarter of a second
on the other hand maybe you've designed a page that takes several seconds before
it's presentable regardless if you want to set up a pre loader
here's a quick way to do it one we'll design our pre loader - we'll set our
initial state and three we'll make sure the preloader goes away
once the page is loaded number one we'll drag in a div block from the ad panel
and we'll drag it right into the page body mr. block will be the main
container for our pre loader so we'll create a class and name it free
loader let's make some adjustments first will enable flexbox and we'll justify
and align its children to the center second we'll adjust the positioning
setting the position to fixed we'll make sure to select full so it fills up the
whole viewport and we'll set the z-index to some obscenely high number this means
it'll appear on top of all other elements finally let's set a background
color we can choose a color from the color picker right here and of course we
can drag in anything anything can show up on page load if it's a huge gif for a
video or something it'll probably slow down the page load and serve as an
anatomy of the whole spirit of the pre loading thing so it's up to you we've
just dragged in a text block and we wrote loading and that's it that's the
basic design the bouncing ball the one from the beginning is taught in the full
guide on web player University so check out the link to that in the description
and feel free to skip over to that if you want to build it let's set our
initial state now the first thing we want to do after our design is done
we've simply put the word loading here for now is set the display in the style
panel here to none why because we want to be able to edit on the page without a
giant div block covering our work now notice the preloader div block is still
selected and we'll go over to interactions where we can add a trigger
we'll make sure the trigger is the page loading and we have two options here we
can set it when the page starts loading or we can set it when the page finishes
loading we'll want to go with the second option let's
create a new timed animation here and let's name it we're giving a name to
this animation and this is where we can set our initial state even though we set
the display to none in the style panel we can set our display back to flex
under hide show and we'll simply choose flex this makes it visible again and to
make it the initial state we just flick the switch that's it
part to complete and now for the final part the initial state controls what
everything looks like when the page first comes up we're going to make our
preloader disappear once the page finishes loading we're going to do this
in two steps one we'll add a new point a new action that sets the opacity to 0%
we want this to occur fairly quickly so let's change the duration to drop that a
bit and two after that we want to set our display setting to none after fading
out after the opacity hits zero we'll hide it we'll set our display setting to
none now if we want to ensure that the preloader shows up for a set amount of
time a minimum we can go back to the first action the opacity change and we
can set it to occur after say half a second that means even after the page
loads it'll hold for a half second before starting to disappear and that's
it we create our design set our initial state and animate it out we do all this
on page load when the page finishes loading
that's setting up a pre loading animation
