Add icon before form field

How can I add icons before the form fields?
This is how looks now:
And here how I want:
Here is css code (front.css):
body .qb-form {
width: auto;
height: auto;
}
#media (max-width: 660px) {
body .qb-form {
width: 100%;
}
}
body .qb-form h2 {
background: #3482C3;
padding: 15px 25px;
margin-bottom: 0;
color: white;
margin-top: 0;
}

I will be happy if anyone can help.
Thank you in advance.
Best regards

You can select the input fields from your HTML template by using their id's.
You you use icons8 to find the correct icons.
There you can get the Link (CDN) for each item by clicking on the download button and copy HTML.
You can paste the copied code in your HTML (just before the respective input field).
Afterwards you can style the respective item in your CSS file.
So that it has the same border and height as your input field.

How to place two elements together and next element in next line in form CSS and HTML?

I am beginner in HTML,CSS,JavaScript
I wish to place "enter username" box and "OK" image together, the OK image should be next to input box, and the next elements next in next line.
.check1 {
display: inline;
margin-right: -4px;
float: inline-end;
}
.check2 {
display: inline;
margin-right: -4px;
float: inline-start;
}
.login-form {
margin: 50px auto;
width: 300px;
font-family: Tahoma, Geneva, sans-serif;
}
.login-form h2 {
text-align: left;
color: rgb(124, 34, 105);
}
.login-form input{
width: 100%;
padding: 15px 15px 15px 15px;
margin: 10px 0 10px 0px;
box-sizing: border-box;
outline-color: rgb(38, 179, 235);
}
.login-form button{
width: 100%;
border: none;
cursor: pointer;
padding: 15px;
background-color: rgb(148, 53, 127);
color: white;
box-sizing: border-box;
outline: none;
}
.login-form button:hover {
opacity: 90%;
}
#username {
width: 20px;
height: 20px;
}
#password {
width: 20px;
height: 20px;
}
<!DOCTYPE html>
<html>
<head>
<title>Welcome</title>
<link rel="stylesheet" href="css/main.css"/ >
</head>
<body>
<div class="login-form">
<h2>Student Record Management</h2>
<form action="auth" method="POST">
<div class="check1">
<img id="username" src="ok.png" alt="ok">
<input type="text" name="userid" placeholder="Enter Username" required autofocus autocomplete="off" / >
</div>
<div class="check2">
<input type="password" name="password" placeholder="Enter Password" required / >
<img id="password" src="wrong.png" alt="wrong">
<div>
<button type="submit">Login</button>
<label><pre>Create account here</pre></label>
</form>
</div>
</body>
</html>
the next element should be in next line and same the box and the image should be in same line.
and if someone tells me how to access the HTML elements in JavaScript
would be really appreciated.

This code will align the input box and ok image as an inline element.
.check1 {
display: flex;
flex-direction: row-reverse;
margin-right: -4px;
float: inline-end;
}

Can you please check the below code? Hope it will work for you. We have used display:flex in check1 and check2 and applied margin-right to input element as per your requirement
Please refer to this link: https://jsfiddle.net/yudizsolutions/vpr7qLy6/

if statement not working and stopping the whole function from working

Hi can't get my "if" statement to work. When I write my if the whole function stops working. Without the if, everything works fine.
I tried everything, at least everything I could come up with, which means the use of parseInt, if/else, I read the code again and again, I changed parenthesis, I researched on google. Still nothing. I need a little help!
function myF() {
var num1 = document.getElementById("a").value;
var num2 = document.getElementById("b").value;
var num3 = document.getElementById("c").value;
var num4 = document.getElementById("d").value;
var num5 = document.getElementById("e").value;
var num6 = document.getElementById("f").value;
var num7 = document.getElementById("g").value;
var num8 = document.getElementById("h").value;
var num9 = document.getElementById("i").value;
if (isNaN(num1) || num1 = "") {
num1 === 0;
}
var total = parseFloat(num1)+ parseFloat(num2)+parseFloat(num3)+parseFloat(num4)+parseFloat(num5)+parseFloat(num6)+parseFloat(num7)+parseFloat(num8)+parseFloat(num9);
var floating2 = document.getElementById("result").value = total.toFixed(2);

In the if statement, you should use === to test for equality. = is the assignment operator, which you should in the line below, i.e. num1 = 0;.

And this is my LoginValidate.js
function loginValidate() {
var valid = true;
var validationMessage = 'Please correct the following errors:\r\n';
document.getElementById('errorUserNameMissing').style.display = 'none';
document.getElementById('errorPasswordMissing').style.display = 'none';
if ((document.getElementById('uname').value = 'Enter Username…')||(document.getElementById('uname').value.length == 0) ){
validationMessage = validationMessage + ' - UserName is missing\r\n';
document.getElementById('errorUserNameMissing').style.display = 'block';
valid = false;
} else {
document.getElementById('errorUserNameMissing').style.display = 'none';
}
if ((document.getElementById('pass').value = 'Enter Password…')||(document.getElementById('pass').value.length == 0) ){
validationMessage = validationMessage + ' - Password is missing\r\n';
document.getElementById('errorPasswordMissing').style.display = 'block';
valid = false;
} else {
document.getElementById('errorPasswordMissing').style.display = 'none';
}
if (valid == false) {
alert(validationMessage);
}
return valid;
}
please some one help in validating the login page with errors on not providing any input(it should display respective error message).
Thanks in advance

In the JavaScript
document.getElementById('uname').value
returns "Enter Username…" that is the default value and
document.getElementById('uname').value.length
returns 15 that's why the condition is not matched.
You have to check for default value along with length.
document.getElementById('uname').value = 'Enter Username…'
But once this field is focused the value is empty and it works fine.

your code provide null pointer exception here
document.getElementById('errorPassWordMissing').style.display = '';
exception raise and your function does not return false and form post data.
use placeholder property instead of value and focus event, for example
<input type="password" name="txtPassword" id="pass" placeholder="Enter password…" />
also may be you should use jQuery and validation plugin
http://plugins.jquery.com/validate/

One obvious problem I can see. This is wrong:
document.getElementById('errorUserNameMissing').style.display = '';
You shouldn't be setting style.display to a blank string. It should be one of the standard CSS display types, like "inline" or "block" (and there are other types).

I've created a JSBin with my code so far, including CSS and JS files: http://jsbin.com/oligol/1/edit

showErrorAndFocusIf('FieldData1', isEmpty, 'messageError');
/* For debugging, lets prevent the form from submitting. */
if (formIsValid) {
alert("Valid form!");
return false;
}
return formIsValid;
}
function showErrorAndFocusIf(fieldId, predicate, errorId) {
var field = document.getElementById(fieldId);
if (predicate(field)) {
document.getElementById(errorId).style.display = 'inline';
if (field.select) {
field.select();
}
field.focus();
return false;
}
return true;
}
function isEmpty(field) {
return field.value == '';
}
function isAnInvalidEmail(field) {
var email = field.value;
var ok = "1234567890qwertyuiop[]asdfghjklzxcvbnm.#-_QWERTYUIOPASDFGHJKLZXCVBNM";
for(i = 0; i < email.length; i++){
if(ok.indexOf(email.charAt(i)) < 0) {
return true;
}
}
re = /(#.*#)|(\.\.)|(^\.)|(^#)|(#$)|(\.$)|(#\.)/;
re_two = /^.+\#(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;
return re.test(email) || !re_two.test(email);
}
function hideAllErrors() {
/*document.getElementById("nameError").style.display = "none"*/
document.getElementById("emailError").style.display = "none";
document.getElementById("emailError2").style.display = "none";
/*document.getElementById("categoryError").style.display = "none"*/
document.getElementById("messageError").style.display = "none";
}

A few points:
Your HTML is invalid, you should something like the W3C Validator to check your HTML.
You element names and ids are inconsistent. E.g. Your "Name" field is named "txtName" but has the id "name" and your "E-mail address" field is named "FieldData1" but has the id "FieldData2". Use consistent and sensible names so that the HTML and JavaScript are easy to write and understand.
You've broken the JavaScript by removing the AND operators (&&) in the checkForm function. The showErrorAndFocusIf function returns a boolean value that is true when the specified field is valid. The return values of the calls are supposed to be combined for all of the validation constraints to determine if the whole form has passed validation.
Lastly, the ids of the fields and error messages used in the JavaScript did not match the HTML. The JavaScript uses the DOM's getElementById function to retrieve references to the fields and the error messages in the HTML, so you have to make sure that the ids match in order for the code to work.
I've corrected these problems in a new JSBin: http://jsbin.com/otinoz/2/edit
