I have a problem with displaying the input in a div in my calculator. It doesn't display anything. What am i doing wrong? I am pretty new to PHP, so please explain as much as possible, so that I could learn from this. If it is possible, then the variable should be constantly refreshed, so that it is always the latest input. This is my code, the problem can be found in the PHP part of the code:

You don't use var when declaring variables in PHP. Just $. And learn about "scope". You were trying to use a variable you declared outside of the function, in the function. Which doesn't work. So in my code, I passed that variable as a parameter to be used inside the function.
I gave you a lot of key words and a basic explanation for you to do some more digging.
EDIT: And I don't think that while loop will do anything. While what? Something needs to go inside those parenthesis. What are you looping through?
For PHP you need a php-enviroment like apache with php (for beginners: use "xampp")
this file needs normally the file-ending .php so the serverside-parser can parse your php-code in your file.
Here I have taken snippet from your code.
<div id="display">
<?php
var $input = "0";
function showInput() {
echo $input;
};
while () {
showInput();
};
?>
</div>
Just change your code with mine below.
<div id="display">
<?php
$input = "0";
echo $input;
?>
</div>
Let me explain it.
$input = "0";
THe above line just initializing the value for our input variable, you can change 0 with any value you like.
echo $input;
This will echo out the value saved inside our input variable in first line of PHP code above. If you have declared another variable you can also echo that just change the variable name after $ sign. $ sign let the PHP know that its variable name starting up.
Correct those parts into these and your code will work
<div class="row">
<div id="9" class="button">
9
</div>
<div id="6" class="button">
6
</div>
<div id="3" class="button">
3
</div>
<div id="equal" class="button">
=
</div>
</div>
<div class="row">
<div id="plus" class="button">
+
</div>
<div id="minus" class="button">
-
</div>
<div id="multiply" class="button">
x
</div>
<div id="divide" class="button">
/
</div>
<div id="display">
<?php
function showInput() {
$input = "0";
echo $input;
}
?>
</div>
</div>
You haven't set an argument in the while loop. While what exactly? Also you need to look up variable scope. Functions can not access variables that are not contained within the function, in this case parse them in. eg
<?php
$input = "0";
function showInput($input)
{
echo $input;
};
showInput($input);
?>
Here is an example of your code working with my edits http://phpfiddle.org/main/code/1nh-wda

I am across a little bit confusing problem. I want to display an alert message on the top of the screen when the account is activated. but problem is that when messages shows, the welcome blue box moves down which I don't want. When I close the alert message the content comes in their real position.
This is the html code
<!DOCTYPE html>
<html>
<head>
<?php include_once('head.php'); ?>
<title>Sign Up</title>
</head>
<body>
<?php
if(isset($_SESSION['act'])) ?>
<div class="text-center alert alert-primary alert-dismissible fade show" role="alert">
<?php echo $_SESSION['act']; ?>
<button type="button" class="close" data-dismiss="alert" aria-label="close">

This is the css code
/*Message box*/
.message-inner-box{

border-radius: 50%;
margin-top: -3.2em;
margin-left: -5em;
background-color: var(--message-box-color);

align-items: center;
}

}
.title-container p {
margin: 0;
}
.heading {
font-size: 1.3em;
font-weight: 600;
}
.subheading {
font-size: 2em;
font-weight: 800;
}
/*Sign Up page*/
.signUp-image {
height: 60%;
width: 60%;
}
.signuUp-header {
padding-top: 5rem;

You can add the style property to the alert div to include a negative bottom margin that repositions the element under this alert box.
<div style="margin-bottom: -50px" class="text-center alert alert-primary alert-dismissible fade show" role="alert">
code:

So, How can I fix this problem? Please help me.
Thank You
You can apply the style sheet too both print and screen using media='screen,print'
<link ../bootstrap.min.css' rel='stylesheet' media='screen,print'>
or
<link ../bootstrap.min.css' rel='stylesheet' media='all'>
When we want to apply some style when printing a page, we need to apply the styles using #media print. Then only the style will apply for windows print function.
Style.css
#media print
{
.center {
float: left;
text-align: center;
}
.center h3 {
color: #000;
font-weight: 600;
}
.left {
font-size: 14px;
float: left;
width: 30%;
color: #000;
}
.right {
font-size: 14px;
float: right;
width: 70%;
color: #000;
}
}
Then link the css file where you want to print the page with style.
<link rel="stylesheet" type="text/css" href="Style.css">
Call the Print Function on Button Click
<button onclick="printPage()" class="center">Print</button>
<script>
function printPage()
{
print();
}
</script>
I want to create the same of that html style with wordpress contact form 7 , i just need to make that design work functional with wcf 7
Link
and my example html code :
<div class="form-group">
<label>Destination(s)</label>
<ul class="tags">Fes</ul>
<ul class="tags">Hight Atlas Mountains</ul>
<ul class="tags">Marrakech</ul>
<div class="destinations-wrap">
<input type="text" class="form-control icon icon-location" name="locations_search" placeholder="e.g. Iceland"
autocomplete="false">
<input type="text" class="destinations-suggestion" disabled>
</div>
<button class="btn btn-primary destinations-wrap-btn" tabindex="-1">+ Add Another</button>
</div>

But my css doesnt work good. I add css as .
I get this result:
So how can I solve this problem?
Maybe I must set some settings for my css or settinhs for page?
Thanks for any help.
I am pretty sure that float is the cause of the problem
Depending on the dompdf version you can use def("DOMPDF_ENABLE_CSS_FLOAT", true); in dompdf_config.inc.php but this is not a good practice
I would suggest to use display:inline-block or even position:absolute which are fully compatible.
I have inside the loop two DIV and I need put a style to one and another to the other DIV.
I do not know if I can do it with PHP, JS or CSS. This is my code:
-- the styles (this styles are in the same page, because I have a general style that I include) --
<?php
$style_1 = '<style>
.content .postcontent-0 .layout-item-0 { margin-bottom: 7px; }
.content .postcontent-0 .layout-item-1 { border-spacing: 10px 0px; border-collapse: separate; }
.content .postcontent-0 .layout-item-2 { border-top-style:solid; background: #ffffff; }
</style>';
$style_2 = '<style>
.content .postcontent-0 .layout-item-0 { color: #083752; background: ; border-collapse: separate; }
.content .postcontent-0 .layout-item-1 { color: #083752; }
.content .postcontent-0 .layout-item-2 { border-style:Double; border-radius: 15px; }
.content .postcontent-0 .layout-item-3 { padding-right: 10px;padding-left: 10px; }
</style>';
?>
-- the view
<?php for ($i = 0; $i < $contador; $i++) { ?>
<!--Here begin the STYLE_1-->
<div class="content-layout-wrapper layout-item-0">
<div class="content-layout layout-item-1">
<div class="content-layout-row">
<div class="layout-cell layout-item-2">
<p> Text #1 </p>
</div>
</div>
</div>
</div>
<!--Here END the STYLE_1-->
<!--Here begin the STYLE_2-->
<div class="postcontent postcontent-0 clearfix">
<div class="content-layout-wrapper layout-item-0">
<div class="content-layout-row">
<div class="content-layout layout-item-1">
Text #2
</div>
<div class="layout-cell layout-item-2" >
<p>
Text #3
</p>
</div>
</div>
</div>
<div class="content-layout">
<div class="content-layout-row">
<div class="content-layout layout-item-3">
<p>Text # 4</p>
</div>
</div>
</div>
</div>
<!--Here END the STYLE_2-->
<?php } // for i ?>
You can use different class name for two separate div but if you want to use this without change the existing class name then use inline css.Try this code:
<?php for ($i = 0; $i < $contador; $i++) { ?>
<!--Here begin the STYLE_1-->
<div class="content-layout-wrapper layout-item-0" style="margin-bottom: 7px;">
<div class="content-layout layout-item-1" style=" border-spacing: 10px 0px; border-collapse: separate; ">
<div class="content-layout-row">
<div class="layout-cell layout-item-2" style="border-top-style:solid; background: #ffffff;">
<p> Text #1 </p>
</div>
</div>
</div>
</div>
<!--Here END the STYLE_1-->
<!--Here begin the STYLE_2-->
<div class="postcontent postcontent-0 clearfix">
<div class="content-layout-wrapper layout-item-0" style="color: #083752; background: ; border-collapse: separate;">
<div class="content-layout-row">
<div class="content-layout layout-item-1" style="color: #083752;">
Text #2
</div>
<div class="layout-cell layout-item-2" style"border-style:Double; border-radius: 15px;">
<p>
Text #3
</p>
</div>
</div>
</div>
<div class="content-layout">
<div class="content-layout-row">
<div class="content-layout layout-item-3" style="padding-right: 10px;padding-left: 10px;">
<p>Text # 4</p>
</div>
</div>
</div>
</div>
<!--Here END the STYLE_2-->
<?php } // for i ?>
