Hi,
1. Regarding the quantity box, I think that some code like this will do the job :
.hikashop_product_stock td {
vertical-align: top !important;
}
2.
- For the payment line :
.hikashop_payment_methods_table td {
vertical-align: top !important;
}
- For the shipping line :
#hikashop_shipping_methods td {
vertical-align: top !important;
}
3. And for your Edit button I think that the problem is coming from the code of your template
bootstrap.css file :
.modal {
position: fixed;
top: 10%;
left: 50%;
z-index: 1050;
width: 560px;
margin-left: -280px;
background-color: #fff;
border: 1px solid #999;
border: 1px solid rgba(0,0,0,0.3);
*border: 1px solid #999;
-webkit-border-radius: 6px;
-moz-border-radius: 6px;
border-radius: 6px;
-webkit-box-shadow: 0 3px 7px rgba(0,0,0,0.3);
-moz-box-shadow: 0 3px 7px rgba(0,0,0,0.3);
box-shadow: 0 3px 7px rgba(0,0,0,0.3);
-webkit-background-clip: padding-box;
-moz-background-clip: padding-box;
background-clip: padding-box;
outline: none;
}
