I found a code for you to move the mouse and display a text, I would like it to show a photo.
Can be done with css or javascript but I do not know the part of the photo. type this
<style>
#mostrar{<br />
display:none;<br />
}<br />
</style>
<div id="passar_mouse">Passar o mouse</div>
<div id="mostrar">http://tcgbrasil.com/wp-content/uploads/2017/08/Sem-Título-1-600x600.png</div>
<script>
$('#passar_mouse').mouseover(function(){
$('#mostrar').css('display', 'block');
});
$('#passar_mouse').mouseout(function(){
$('#mostrar').css('display', 'none');
});
</script>
But I would like the image to appear floating, I'll show you what I already have, but it's a wordpress plugin.
