Truco:
Como poner el código para poner nieve cayendo en tu blog
Durante estos días he añadido un script en el blog, para que se viera nieve cayendo en la página. ¿como se hace?
1) Pues te vas a la página de Diseño
2) Se le coloca un nuevo gadget del tipo "html/javascript"
3) y se le pega el siguiente código:
<script type="text/javascript">
//Configure below to change URL path to the snow image
var snowsrc="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiTt2vMifRdQzrsJVmTZEcrDQFi1Ebc2sff6momVbWK5R5dEH_XXfAwlRiPo9Hg9GiszbW-xH6NwSNaVRILua-vKQlnoU42hh70G_jBB7bcft6HnH6aw7qjzE4Qo0xKYxU0xFEyzbECZG8/s400/snow.gif"
// Configure below to change number of snow to render
var no = 30;
// Configure whether snow should disappear after x seconds (0=never):
var hidesnowtime = 0;
// Configure how much snow should drop down before fading ("windowheight" or "pageheight")
var snowdistance = "pageheight";
///////////Stop Config//////////////////////////////////
