Fixed bar in CSS footer does not display correctly on iPad

I have a div to stay in the footer, but when accessed by the iPad it creates a distance from the last DIV with the fixed DIV of the footer.

CSS:

.fixo-modelo-3-1 {
position: fixed;
width: 100%;
height: 43px;
left: 0;
bottom: 0;
background-color:#FFFE62;
}
