Form width on my account pages

Hi,

I am struggling with the common problem of to short form fields. After some updates woocommerce check out page and the login-in + my acount pages have way to small column widths.

For the check out page I added a general custom CSS code:

.woocommerce span.onsale{display:none;}
#wcvat_notpossible { display: none; }
.woocommerce-checkout .col-1, .woocommerce-checkout .col-2 {
max-width: 100%;
}
.woocommerce-checkout .form-row {
display: block;
}

Check out looks good now.

But I am struggling with login form and my account subpages.
I tried this CSS code:

.col-1,
.col-2 {
max-width: none !important;
}

The form fields are wider now, but they still look not formatted well. (not block-style, every line has different width.)

Any ideas anyone? Thanks in advance!
