if I try to remove the margins by expanding the width of the signel tabs the icons disappear, and the tabs are no longer clickable.

i try with this css

.tab-acc {
background-color: #387ef5;
width: calc(100% / 3);
background-position: center;
}

.tab-activ {
background-color: #ef473a;
width: calc(100% / 3);
}

.tab-home {
background-color: #33cd5f;
width: calc(100% / 3);
}

the result is this
