I will take the first post:
Your theme has this CSS:
.traveltour-body h4 {
color: #383838;
font-size: 28px;
font-family: "Poppins", sans-serif;
margin-top: 0px;
margin-bottom: 20px;
line-height: 1.2;
font-weight: 700;
}
To control this, you need custom CSS like this:
`.traveltour-body .searchandfilter[data-sf-form-id=”22″] h4 {
/* CSS rules */
}
To the second question:
I am not sure if that date will be a problem in that format. Maybe, maybe not. You would need to test. Ideally, it should be 20200918
for example. It should not matter that it is not datetime.
At the moment, you need to use both From and To. The To field can be hidden, and you can use JavaScript to fill it with a long away date when the page opens. We will change/enhance the form field date match/range options in V3, due in a few months.
