K2 and t3 bs3 blank template

I had this problem to edit on fron-end whit K2 articles and solved from admin whit this code to put in
custom.css

/* Custom style by user here */

.itemEditLink .modal {

display: inline-block;

position: inherit;

width: auto !important;

top: auto !important;

overflow: hidden;

}

(i don't know why this discussion went deleted so i replace this)

Now i have a new problem whit K2
