Layout changes when I switch resolution - html

I'm making a website (in Dutch) and I work on a laptop with a external screen. The external screen has another resolution then my laptop screen so the site comes out distorted when viewed on the other screen. How do I fix this?

I think it's because you're using the width as a percentage, then positioning your buttons absolutely. This means that the 100% value will adapt to the screen size but not the buttons' positions as they will always be absolutely positioned using the same values for each screen.
One solution could be to use one precise width value, another solution would be not to absolutely position the buttons and instead use the floatproperty for the buttons. Hope this helps.

Create a <div> on top of another <div>

I'm trying to create a div (text) on top of another div (rotated white plane). When I create a new div the text is being placed behind and on a lower layer as the previous plane. This is the current website (I'm trying to get text under the bottle image):

you can try giving z-index to the div maybe z-index is the order of something in the z dimension lets say if you want the second div to be in front you can give it the z-index of one
the code looks like this:
z-index:1;

Adding <!DOCTYPE html> removes my container background

I've been working on a website as a first year project, this is our first website that we need to make but i found out that we were supposed to use the <!DOCTYPE html> instead of <html> (which was told later on) but now that i do that, the background of my container/content div disappears and only shows a bit when i put a letter inside of it.

The background of the content/container should be light gray
As already stated in the other answers you still need the <html> tag. Footer you said was by accident outside the body but I placed it inside the body in the snippet below. One way to get your elements flowing correctly in your HTML structure is to set float: left; to your #content div.

Niet beat me to it in the comments on your post but #content isn't defined anywhere in your html. I'm assuming that the div with the textClass class is what you want the content to be so just add it to that div as you've done above.
Some other minor points:
You still need the opening <html> tag under your !DOCTYPE definition
<footer> should be inside <body> with everything else
I'd recommend setting those repeated <p> styles in your main content to a containing div such as the offending #content id. The styles will still be pulled through as they are now.
ID content is missing, but i've made some simple changes in css. Is this what you are looking for?

The !doctype html tells your html page which version of HTML are you using.By default , it is the latest version that is HTML 5.
Now, html /html these tags define the starting and ending of your html page.
These are mandatory tags for your HTML page.
And in addition to these tags you use !doctype html tag.
Hope this helps you .
Add the following line after your <body>
<div id="content">
and then make sure to close the div before </body>
As Niet pointed out, you were lacking an element with the id of 'content'
<!doctype html>
does not replace the <html> tag. You need both, see http://www.w3ctutorial.com/tags/tag_doctype.
<!DOCTYPE html>
<html>
<head>...</head>
...
</html>
Does that help?

Location of <a> buttons does not stick to its location

CBroe is correct Lucas. Set the div #clicker to position: absolute;. Make sure it's parent #text-marge is set to position: relative;.
You can position elements that are declared as absolute by using top/bottom etc. find out more here.
Also read this as to why its parent should be relatively positioned.

dropdown menu is behind tag

I've made a dropdown menu, but now it's behind another div. I don't know how this happened and I've never had it before. Please help how I can fix this and that the dropdown menu isn't behind some text.

Modify the css adjust z index and position It will work.
#ul-nav {
list-style-type: none;
position: absolute;
width: 100%;
height: 100%;
z-index: 10;
background-color: rgba(0,0,0,0.5);left: 50%;
right: 50%;
transform: translate(-50%, 0px); /*Zorgt er voor dat hij precies in het midden is*/
}
This is because you are using absolute positioning for your container.
#container_header {
position: absolute;
width: 900px;
}
If you remove position: absolute you'll see that the drop down behaves as expected.

Responsive menu html css on small screens

I want to make a responsive menu with only html and css , no Javascript.

It would make more sense to use a responsive framework, such as Bootstrap, or Foundation.
Here is a simplistic example for a responsive navigation menu which utilises bootstrap.
Responsive navigation bar Preview
Responsive navigation bar Download
You have this:
.hamburger ul{
position: fixed;
width: 240px;
height: 100%;
top:300px;
left: -240px;
background-color: #e34dd2;
color: white;
}
position: fixed; means that its position values are in relation to the window/viewport. So having left: -240px; will move this element out of the viewport (i.e. make it invisible). Do you really want this? Even if that's intentionally and supposed to work together with this rule
#menu-toggle:checked ~ .hamburger ul{
left:0;
}
...to move it in, they are in the wrong order - the former rule will most likely overwrite the other one, making the element invisible...
