change drop down menu size, title and font + remove quantity

Hi, i am looking to make the "select size" box smaller and just say "SIZE" in the same font as the rest of my site (screenshot of font attached)

and then remove the "Quantity" box if possible ?

Any help would be much appreciated,

You can use this code to Website > Website Tools (under Not Linked) > Custom CSS

.pdp-layout .pdp-details .variant-option select {
    padding-top: 5px !important;
    padding-bottom: 5px !important;
}
div.product-quantity-input {
    display: none !important;
}

@tuanphan thank you, that has reduced the height of the box but do you know how to change the width, and make it just say size.

also can you remove the text above that says SIZE:

thanks

to adjust width & remove "size", use this CSS code

.variant-option-title {
    display: none;
}
.pdp-layout .pdp-details .product-variants {
    max-width: 300px;
}

To remove "select" from dropdown, see this
