How can I set an input element to be immediately ready for the user to type in, i.e, they do not have to click on the input to start typing, as soon as it renders, it displays the flashing vertical line and enables them to type straight away?
You can use autofocus (more info)
<form action="/action_page.php">
First name: <input type="text" name="fname" autofocus><br>
Last name: <input type="text" name="lname"><br>
<input type="submit">
</form>
You should use the attribute autofocus like in this example: https://www.w3schools.com/tags/att_input_autofocus.asp

dynamically increase input type text textbox width according to the characters entering into it

I'm trying to make a text field I'm using get bigger when you add more characters to it, is there any way to do this?
I suprisingly haven't found a way to do this through searching.
For example:
<input type="text" name="firstname" value="John" size="1">
Would turn into
<input type="text" name="lastname" value="John Smith" size="4">
You could turn the <input> element into a <textarea>, then state how many rows and columns you want to have (basically height and width). In addition, the user can adjust it from there! If you're taking form data, it will still be able to be read. Just make sure that when you make the change remove the size=""
its should be adjusted when you enter more characters.
<input type="text" name="FirstName" onkeypress="this.style.minWidth = ((this.value.length + 1) * 7) + 'px';">

placeholder="Enter amount"
pattern="[0-9]*"
onChange={(e) => this.props.updateWillBeCreditedAmount(e.target.value, currentComProfile)
}
