Answer 1

Please insert a Script editor on the page and put the below code in it :

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
    $("input[title = 'Title of your column']").css('width', '200px');
});
</script>

You can check the internal title of column by pressing F12 and then target the box.

I hope this helps !!!
