Changing Option selector format

[Homedicalco]

Hi,

I added my bundles into my option selector, however, it looks awkward.

I want to add a black border around the option selector and have the header just say 'pick your bundle' like how it is in the picture.

Essentially, I want to format it as this store did. I really would appreciate it if someone could help me, both snippets included the format I want and what it currently looks like for me respectively

My Store URL:https://shopstretchnow.com/products/cervical-traction-device

@Homedicalco ,

.product-single select#SingleOptionSelector-0 {
    border: 1px solid #000;
}
.product-single span.variant-label-option-value {
    display: none;
}

Add this css at the bottom of Online Store->Theme->Edit code->Assets->theme.scss.liquid
