Top navigation bar, dropdown overflow problem - html

There is this W3schools example of dropdown in the top navigation bar. In the CSS section of the code, the navbar has property overflow set to hidden. In the HTML section of the code, the dropdown section is a part of the navbar section.
Now as I hover over the dropdown button, the dropdown-content(hidden section) becomes visible(changed the property, display, from none to block) and there is an overflow as the dropdown-content overflows from the navbar section (I even checked using inspect elements the height of the navbar does not change when the dropdown-content is visible).
Now the question is since the overflow property of navbar is hidden, why is the dropdown-content is visible( it is an overflow)? And why the height of navbar not changing (height of navbar is not specified in the styling) and an additional division of significant height got added into it?
Here is the code from the example:
body {
font-family: Arial, Helvetica, sans-serif;
margin: 0px;
}
.navbar {
overflow: hidden;
background-color: #333;
}
.navbar a {
float: left;
font-size: 16px;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}
.dropdown {
float: left;
overflow: hidden;
display: block;
}
.dropdown .dropbtn {
font-size: 16px;
border: none;
outline: none;
color: white;
padding: 14px 16px;
background-color: inherit;
font-family: inherit;
margin: 0;
}
.navbar a:hover, .dropdown:hover .dropbtn {
background-color: red;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.dropdown-content a {
float: none;
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
text-align: left;
}
.dropdown-content a:hover {
background-color: #ddd;
}
.dropdown:hover .dropdown-content {
display: block;
}

Well a few things, the .down-content class is set to position: absolute; which essentially ignores overflow: hidden; as well as the height of the navbar and essentially most other things. Also the navbar does not have a specified height so there really isn't anything limiting it's size.
In this example below I removed position: absolute; from the .down-content class and also added a height of 75px to the .navbar class. Check it out

font-family: Arial, Helvetica, sans-serif;

<h3>Dropdown Menu inside a Navigation Bar</h3>

The dropdown is not considered overflow here. Overflow occurs when the content of an element is too big to fit its specified area. The nav bar does not have a fixed height - the height is determined by its content (including padding). Therefore the dropdown does not "overflow", as the navbar is "flexible" so to speak.

Wrapping select dropdown navigation in nav tag

I have a navigation menu on mobile which is a select field with some Javascript to redirect to the data-href attribute.
<select>
<option value="" data-href="/somepage">Some page</option>
<option value="" data-href="/anotherpage">Another page</option>
</select>
My question is pretty simple: Would it be preferred to wrap a navigation menu of this kind in a <nav> tag?
The nav element defines a set of navigation links.
In your case you seem to have all links in the same select.
If you are using only one select, then I should not use the nav element.
In case you have multiple selects, you can use the nav element to make them into a set.
My question to you is why even use the select elements?
You could make it much easier by using:
body {
font-family: Arial, Helvetica, sans-serif;
}
.navbar {
overflow: hidden;
background-color: #333;
}
.navbar a {
float: left;
font-size: 16px;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}
.dropdown {
float: left;
overflow: hidden;
}
.dropdown .dropbtn {
font-size: 16px;
border: none;
outline: none;
color: white;
padding: 14px 16px;
background-color: inherit;
font-family: inherit;
margin: 0;
}
.navbar a:hover, .dropdown:hover .dropbtn {
background-color: red;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;

<h3>Dropdown Menu inside a Navigation Bar</h3>

but when I open this website in Safari on Iphone I cant use the dropdown it doesnt work. However if I make .dropbtn a button instead of div it works but now validator doesnt except button to have div and a as child. How can I change the code to make the website valid and can be used on Safari at the same time?
While buttons cannot have div or anchor elements as children, they can have span elements.
The following snippet passed W3C validation. Is it a hack?
Possibly, given button elements are not supposed to have interactive content descendants. See e.g. Is it semantically incorrect to put a <div> or <span> inside of a <button>? for discussion and references on this.
On the other hand it gets us round a problem on touchscreens with minimal alteration and minimal JS.

CSS Dropdown menu shows up as horizontal instead of vertical

I'm trying to develop a website using django and I'd like to add a navigation bar dropdown menu, but for some reason, it keeps showing up as horizontal, instead of vertical.
I'm following the tutorial that W3 Schools has on their website https://www.w3schools.com/css/tryit.asp?filename=trycss_dropdown_button
Despite all of my efforts it still doesn't work, I've tried to look at other questions, but most of them seem to be using a different method using lists, or their using a framework like react.
I moved my project over to this jsfiddle.net and that just seemed to make the problem even worse, because now my second list item in the dropdown doesn't show up at all.
Here is the code I'm working with http://jsfiddle.net/iggy12345/ao04gfne/9/
Here is the code pasted below:
My html file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<div class="header">
<a class="active" href="{% url 'home' %}">Home</a>
<div class="dropdown">
Profile
<div class="dropdown-content">
Logout
Customize Profile
</div>
</div>
</div>
</body>
</html>
My css file:
.dropdown {
float: left;
height: 55px;
display: inline-block
}
/* Dropdown content (hidden by default) */
.dropdown-content {
display: none;
position: relative;
top: 55px;
background-color: #f9f9f9;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
/* Links inside the dropdown */
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
text-align: left;
}
/* Add a grey background color to dropdown links on hover */
.dropdown-content a:hover {
background-color: #ddd;
}
/* Show the dropdown menu on hover */
.dropdown:hover .dropdown-content {
display: block;
}
.header {
background-color: #350752;
overflow-x: hidden;
overflow-y: visible;
}
.header > a, .dropdown > a {
float: left;
color: #dcb0f7;
text-align: center;
padding: 14px 16px;
text-decoration: none;
font-size: 17px;
}
.header a:hover {
background-color: #15bccf;
color: white;
}
.header a:active {
background-color: #c7860e
color: white;
}
Edit
I remodelled my css to look like Chaska's answer, but it still doesn't work, I had to make a few tweaks to get it to keep its original look, but now it adds a scrollbar whenever I hover over profile.
Basically, according to the w3 tutorial, the dropdown list should show up under the profile box, but instead, whenever I try to do it, the entries just sit over the profile button, covering it up, and then on top of that, they continue horizontally instead of vertically
Some revises applied to the css. Please read the relevant comment:
.dropdown {
float: left;
display: inline-block;
height: 55px; /* overflow: hidden will hide the dropdown menu, use fixed height instead */
}
/* Dropdown content (hidden by default) */
.dropdown-content {
display: none;
position: absolute;
top: 55px; /* must specify the top position */
background-color: #f9f9f9;
box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
z-index: 1;
}

How do I make this menu + dropdown button responsive?

I've been trying to make my nav (including the "works" dropdown button) responsive by making them appear through the usual three parallel lines on the top right margin that would then display what I've written on the nav bar when clicked from a mobile.
I've been trying for about two hours without a decent result.
I'm pretty sure it's not the hardest thing but I can't seem to get it right. Would love to understand how it works. Here's the desktop size, non-responsive navbar.
Here's the html:
<html>
<head>
<meta charset="UTF-8">

A basic burger-menu can be achieved by doing the following steps:
1) Create a with the class of burger-menu as a previous sibling element of the navigation you want to hide on mobile screen width.
a) You dont want this to show on your desktop medias, so in the css, style it as display: none;
2) Create a media query for the desired device. Let's say 480px for a mobile device.
3) Within this media query, style the navigation that you want to appear on hover (or click) as display: none;
4) Within this media query, style your burger-menu. In my example, I've styled something very basic, for time reasons, but you can research using spans to make a responsive burger menu.
5) Within this media query, declare an on hover pseudo-class for your burger-menu which accesses the hidden navigation. Since you placed the burger-menu as a the previous sibling element of your navigation, you can use the + css rule to target it like so
.burger-menu:hover + .menu {
}
This means that, when you hover over the burger-menu, you will affect the css of .menu. You can place how .menu's styles will be affected in the above CSS selector.
Here is a basic example of how this process works with your code.
Add this to your html, before your .menu <div>
<div class="burger-menu"></div>
<div class="menu">
Add this to your css file, at the bottom
.burger-menu {
display: none;
}
#media (max-width: 480px) {
.menu {
display: none;
}
.burger-menu {
display: block;
background-color: white;
height: 30px;
width: 30px;
position: fixed;
top: 10px;
right: 10px;
}
.burger-menu:hover + .menu {
display: block;
}
}
Typically, you would advance this by using toggleClass with JQuery to add and remove display to your navigation menu on clicking the burger menu.
P.s the benefit of using spans to create your burger-menu will be when you want it to have nice animation, changing from a burger menu to a cross, or arrow, etc.
here is a solution with a responsive menu list. Now you should add this menu list to your project.
function myFunction() {
var x = document.getElementById("myTopnav");
if (x.className === "topnav") {
x.className += " responsive";
} else {
x.className = "topnav";
}
}

I hope you can do something with it and add it to your project ...

Is there a CSS-only way of making dropdown menu items the same size as their parent?

I've been tampering around in W3 Schools and so far I've gotten the desired effect, but the navbar now expands with the dropdown menu. Is there a better way of doing this that I'm missing? Apologies in advance for formatting, and thank you for your time.
EDIT: To hopefully clarify a bit further: Example

The code:

The reason your entire nav is expanding is due to the positioning of the item. You have the .dropdown-content set to position: relative; By changing this to position: absolute; it will fix the first issue.
However, now to get the width the same as the parent, there are a few ways to do this. The easiest would be to simply set a width property to the dropdown-content as well, so it is always the same. The only issue will be if you have longer dropdown content areas so that the words are cut off. If this is the case, you can use min-width instead. I have calculated the width to be 97.45px; from the padding used on the <button> tag.
So all you will need to do is change your css of .dropdown-content to :
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
width: 97.45px;
}
or, like I said min-width: 97.45px; . This will keep it the same width as the parent while allowing options to expand with larger content.
If this isn't what you're looking for, please comment reply to this and I'd be happy to help. There's a few different ways to accomplish this. Purely setting a width might just be the most simple. Btw, welcome to Stack Overflow
