Start tag head seen but an element of the same type was already open.
also I got some other errors:
" Saw <?. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.) "
and
" No p element in scope but a p end tag seen. "
I have no clue how to fix them.

There were some added characters under div#strona that were interfering with how the code was being run.
In order to make the Javascript functional, add the clickbutton1() onclick function directly to the HTML element.
Below is the reformatted code with HTML/CSS/Javascript in their own respective files:
function clickbutton1() {
return document.getElementById("opis").innerHTML = Date();
}
html,
body {
margin: 0;
padding: 0;

#weemizo Yes! I added the CSS styles to a style tag and the JS into a script element. They are now both placed in the head tag.

I am trying to find a javascript code for a word searcher in a text (through a form and a search button). Ι have found one which can search many words at the same time, but they need to be in a row. If the words are mixed it doesn't work. What kind of updates should we make?
Please advise

To search many words mixed
As I don't exactly know what methods you would like to use. I can't fully answer.
But take a look at this js method: https://www.w3schools.com/jsref/jsref_includes.asp
Why doesn't it count styles and write an error, how can I fix it? It seems that he indicated all the paths correctly, connected styles and scripts, but he either does not read them at all (styles) or displays such an error. Here is the code html, javascript, css.
How can you fix this error? And in general not so?

<a class="cookie_btn" href="#politika">privacy policy</a>
</div>
</div>

</html>
JS:
function getCookie(name) {
let matches = document.cookie.match(new RegExp(

return matches ? decodeURIComponent(matches[1]) : undefined;
}
let cookiecook = getCookie("cookiecook"),
cookiewin = document.getElementsByClassName('cookie_notice')[0];
if (cookiecook != "no") {
cookiewin.style.display="block";
document.getElementById("cookie_close").addEventListener("click", function(){
cookiewin.style.display="none";
let date = new Date;
date.setDate(date.getDate() + 1);
document.cookie = "cookiecook=no; path=/; expires=" + date.toUTCString();
});
}

why don't you try to make the tag at the bottom.
like this:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="style.css">
<TITLE></TITLE>
</head>
<body>
<div class="cookie_notice">
This site uses cookies
<div>
<a class="cookie_btn" id="cookie_close" href="#close">Agree</a>
<a class="cookie_btn" href="#politika">privacy policy</a>
</div>
</div>
<script src = "script.js">
</script>
</body>
</html>
here you go
HTML is read from top to bottom, so the script is called before the rest of the page is rendered.
cookiewin = document.getElementsByClassName('cookie_notice')[0];
This line of code is accessing a element which hasn't loaded yet resulting in undefined. To fix this problem simply place the script tag at right before the closing body tag.
I am trying to get a JavaScript listener to work but nothing changes.
Here is the full code:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
#trigger {
padding: 20px;
background-color: red;
border: 1px solid white;
width: 100px;
cursor: pointer;
}
#box {
padding: 20px;
background-color: green;
border: 1px solid white;
width: 100px;
cursor: pointer;
}
</style>
</head>
<body>
<div id="trigger">Click Here</div>
<div id="box">
content should change
</div>
<script type="text/javascript">
document.addEventListener("click", () => {
document.getElementById("trigger"), () => {
document.getElementById("box").innerHTML = "New Box Text";
}
});
</script>
</body>
</html>
I know I can do this using jQuery, but I want to do it with just pure, vanilla JavaScript.
When I click on #trigger, #box text is not changing. What I'm I doing wrong?
In order to run your code only, when the DOM completely loaded and parsed, add an evenet listener under the DOMContentLoaded event, then use querySelector to select the element with the #trigger id, then add a click event listener to it and use querySelector again to select the element with #box id and modify its .innerHTML accordingly:
document.addEventListener('DOMContentLoaded', () => {
document.querySelector("#trigger").addEventListener('click', () => {
document.querySelector("#box").innerHTML = "New Box Text";
});
});
The great thing about using querySelector and also querySelectorAll is that they provide a similar functionality compared to jQuery, when selecting elements.
Example:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
#trigger {
padding: 20px;
background-color: red;
border: 1px solid white;
width: 100px;
cursor: pointer;
}
#box {
padding: 20px;
background-color: green;
border: 1px solid white;
width: 100px;
cursor: pointer;
}
</style>
</head>
<body>
<div id="trigger">Click Here</div>
<div id="box">
content should change
</div>
<script type="text/javascript">
document.addEventListener('DOMContentLoaded', () => {
document.querySelector("#trigger").addEventListener('click', () => {
document.querySelector("#box").innerHTML = "New Box Text";
});
});
</script>
</body>
</html>
Add the listener to the box element rather than the entire page:
document.getElementById("trigger").addEventListener("click", () =>
document.getElementById("box").innerHTML = "New Box Text"
);
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
#trigger {
padding: 20px;
background-color: red;
border:1px solid white;
width: 100px;
cursor: pointer;
}
#box {
padding: 20px;
background-color: green;
border:1px solid white;
width: 100px;
cursor: pointer;
}
</style>
</head>
<body>
<div id="trigger">Click Here</div>
<div id="box">
content should change
</div>
</body>
</html>
Sorry to ask but I have searched but coming up with nothing.
I have some divs ( I know everyone has a 'div' ) and I want to add feeds\content
See my code below, in these 'widgets' can I add things like twitter and my email and a news feed?
also not to be too picky, can I just get text only ?
How do I go about it ? Is their something
here is the html, jquery and css code...

I am trying to make a banner, where there should be some text going down from the top to the bottom. The code is just for a test, to see if it is working, so I will optimize it later. I have made this code:
<!DOCTYPE html>
<html>
<head>
<style>
div.background {
background: url(banner.jpg) repeat;
border: 2px solid black;
}
div.transbox {
margin: 30px;
background-color: #ffffff;
border: 1px solid black;
opacity:0.6;
filter:alpha(opacity=60);
width: 200px;
height: 500px;
}
div.transbox p {
margin: 5%;
font-weight: bold;
color: #000000;
}
#animation{font-size:20px; margin-top:40px; margin-left:50px;}
</style>
<script>
function loadImage() {
$("#animation").animate({ marginTop: "300px" }, 1500 ).animate({ marginBottom: "40px" }, 800 );
}
</script>
</head>
<body onload="loadImage()">
<div class="background">
<div class="transbox" id="animation">
<p>Text to fly in</p>
</div>
</div>
</body>
</html>
If I put an alert("test"); in the javascript code, I get the alert. But when I try to animate something, nothing happen. So I guess it is the animation code in the javascript, there is something wrong with? Can anybody see what I am doing wrong?
Best Regards
Mads
1 Include JQuery library.
2 Use absolute values in animate function:
$("#animation").animate({ top: 300 }, 1500 ).animate({ top: 40 }, 800 );
For this you need to make your <div class="transbox" id="animation"> as absolute positioned.
You are using Jquery here you just forget to include it into your code:
Working Code:
<!DOCTYPE html>

}
div.transbox p {

.animate() is the jQuery function. You need to include the jQuery library to use it.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

}
div.transbox p {

font-weight: bold;

}
#animation{font-size:20px; margin-top:40px; margin-left:50px;}
</style>
<script>
function loadImage() {
$("#animation").animate({ marginTop: "300px" }, 1500 ).animate({ marginBottom: "40px" }, 800 );
}
</script>
</head>
<body onload="loadImage()">
<div class="background">
<div class="transbox" id="animation">

Just include jQuery lib in your page in header section
