Hi Tom,
thank you.
I tried with this code
<style>
.listbox {
background-color: rgba(255,194,51,0.1);
border: 10px;
box-shadow: 1px 1px 5px 0px rgba(0,0,0,0.5);
}
</style>but (the list in the bottom) now has the border only on the left and in the bottom.
Until now I tried to avoid to learn code but it seems I have to ;). Can you please help me how to have the same border an all sides and probably you can suggest me a simple tutorial to learn some basic code.
