Unable to change buttons

im trying to change some buttons but i only manage to change one, i looked at the examples in yor demo page but i cant change them, the only one i manage to it was the css

.hikashop_product_quantity_main .hikashop_product_stock td a {
background-color:transparent;
background-image:url("../images/add_icono.png");
background-repeat:no-repeat;
color: #ffffff;
font-weight: bold;
margin-top: 3px;
padding: 3px 7px

}

but i couldnt change the form .hikashop_cart_input_button, or the .moduletable-cart .hikashop_cart_input_button.

i have ccs buttons turned off in component

Solved, names for the css are not the same in my web, for example the cart module checkout button is .hikashop_cart .button.hikashop_cart_input_button instead of .moduletable-cart .hikashop_cart_input_button. thank you
