 Falling Snow, Leaves, Ornaments, Text and any other image you want to fall down on a page 

The elements on this page are just for a DEMO, but would be too busy for an actual page or not?

Refer to this for color names: http://www.w3schools.com/colors/colors_names.asp

mycolor is an optional list of colors - defaults are shades of white
myfonts are optional fonts, see this for font names: http://www.w3schools.com/cssref/css_websafe_fonts.asp
myimages are optional images or text lines to display - from 1 to as many as desired.

The one below is just for demonstration to show how you can combine various elements.

There are four predefined displays:

"snow"  shows snow images
"snowalt"  shows alternative snow images (more variation)
"snow*" shows character *+. snow
"leaf"    shows falling leaf images
"ornament" shows falling ornaments
"balloon" shows rising balloons
"firework" shows rising fireworks
"valentine" shows falling hearts and lips
"saintpatrick" shows falling hats and shamrocks
"halloween" shows falling bats

You can vary the number of elements, the speed, the maximum size, the minimum size, fonts and text colors. However, they are all optional.  See example below that shows them all being used for this page.

Examples of using a predefined display. The next script src= is always required for all the examples.

<script src="https://www.classcreator.com/000/7/7/0/13077/userfiles/file/snow/snow-and-more.js"></script>

animate is 0 if you do not want animation and animate is 1 if you do want animation (Do not type animate)

<script>window.onload= MakeSnow("snow",animate);</script>  // generates snow

<script>window.onload= MakeSnow("snowalt",animate);</script>  // generates snow alternative images

<script>window.onload= MakeSnow("snow*");</script>  // generates character snow

<script>window.onload= MakeSnow("leaf",animate);</script>  // generates leaves

<script>window.onload= MakeSnow("ornament",animate);</script>  // generates ornaments

<script>window.onload= MakeSnow("balloon",animate);</script>  // generates balloons

<script>window.onload= MakeSnow("firework",animate);</script>  // generates fireworks

<script>window.onload= MakeSnow("valentine",animate);</script>  // generates valentine

<script>window.onload= MakeSnow("saintpatrick",animate);</script>  // generates saintpatricks

<script>window.onload= MakeSnow("halloween",animate);</script>  // generates halloween

Display is "responsive" if the screen area changes. Display adapts when the elements reach the bottom (or top).
