I found the line-height and text size was adjusted on my landing page. I had success using this code:
@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
.mktoForm input[type=date], .mktoForm input[type=email], .mktoForm input[type=number], .mktoForm input[type=tel], .mktoForm input[type=text], .mktoForm input[type=url], .mktoForm select.mktoField, .mktoForm input[type=date], .mktoForm input[type=email], .mktoForm input[type=number], .mktoForm input[type=tel], .mktoForm input[type=text], .mktoForm input[type=url], .mktoForm select.mktoField {
font-size: 1.3em!important;
line-height:0.5em!important
}
}
