Input:checked + aside, is it possible to target other elements? - html

In my html right now I have the label and input above the aside which I am trying to toggle like so:
<label for="hamburger"><img src="images/hamburger.png"></label>
<input type="checkbox" id="hamburger" />
<aside>
<!-- stuff -->
</aside>
<main>
<!-- stuff -->
</main>
To make things a little complicated, the hamburger only shows up once we reach a media query of max-width 768px like so:
#media(max-width:768px) {
aside {
margin: -335px;
}
main {
margin-left: 0;
}
label {
position: absolute;
top: 20px;
left: 25px;
width: 25px;
height: auto;
display: block;
cursor: pointer;
}
#hamburger:checked + aside {
margin: 0px;
}
}
So what happens is the aside gets pulled to the left, which makes it invisible, the main now fills the screen and its margin disappears and the label(#hamburger) shows up. When I click the newly appeared #hamburger it toggles back and forth between the aside showing up and not showing up. The problem I am having is this: I would like for the hamburger to move with the main section as I toggle back and forth, instead of sitting above the aside in the html. But if I move the label and checkbox inside the main I can't target the aside because #hamburger:checked + aside (for the + to work, I need to have it directly above it).
So the question is can I target other class with #hamburger:checked .class {}, because if I can, I cant seem to figure out how. If I cant do that how can I work around it?
I am sorry for the long winded question but I wanted to make sure I'm thorough in explaining my problem.

Hiding nav menu based on Bootstrap breakpoint view

I am using Bootstrap template SB Admin (https://startbootstrap.com/templates/sb-admin/) which has a hide/show side nav using a menu button on click. I want to retain the standard functionality on full screen which defaults to show the side nav unless specifically clicked to close.
On smaller screens/mobile the default behaviour is to hide the side nav unless clicked to open, which is fine however I want the nav to auto-close when clicking outside of the nav div - but only on mobile.
I can't work out how to trigger different behaviour based on breakpoints - any ideas would be greatly appreciated. Thanks.
Are you using the dist files or src files?
If you are using the dist files you can simply add this to your css, no extra jquery or js required.
#media (max-width: 992px) {
.sb-sidenav-toggled #sidebarToggle::before {
content: '';
position: fixed;
display: block;
z-index: 0;
top: 0;
left: 225px;
bottom: 0;
right: 0;
}
}
What this does is when the side nav is set to open, there is a class added to the body tag. .sb-sidenav-toggled.
We are also wrapping this using a css media query to make sure we are only on tablets/mobiles (991px below).
Then on the #sidebarToggle button (when open using this parent body class .sb-sidenav-toggled) is creating a fixed pseudo ::before element (which is transparent) which covers the body area you want to be clickable to close side nav.
The magic is, because this pseudo element parent is the sidebar nav button, it means when it is clicked it triggers the standard close side nav event. And when it closes, the .sb-sidenav-toggled body class is removed, in turn removing the pseudo element.
If you are using scss files in the src folder, then you can use the sass below...
#include media-breakpoint-down(md) {
#sidebarToggle {
.sb-sidenav-toggled & {
&:before {
content: '';
position: fixed;
z-index: 0;
display: block;
top: 0;
left: 225px;
bottom: 0;
right: 0;
}
}
}
}

Drop down menu hides behind content of page

I'm working on making a Squarespace page with custom CSS to be mobile responsive. In a mobile screen, my page has a drop down menu with the different links for the page. My problem is that in certain pages (such as Music or Watch) when you click on the menu button, the drop down menu hides behind the content of the page. I know this has to do with using position: absolute, but i have not found a way to have the placement of the menu button and drop down list as I want it by using position: relative. This is my CSS for the menu:
#mobileNav {
background: none;
position: absolute;
top: 20%;
left: 0;
right: 0;
}
#mobileNav .wrapper {
border-bottom-style: none;
border-bottom-color: none;
}
You can view the page at richiequake.com using the password Help123. Is there another way I can have the placement of the menu button and the drop down list and have the list "push" the content of the page down so the link list is visible?
Basically, are you are missing is the z-index property. Which will place the container #mobileNav in a higher layer.
By making this change (adding z-index property to your CSS selector):
#mobileNav {
background: none;
position: absolute;
top: 20%;
left: 0;
right: 0;
z-index: 1;
}
I can now see the menu links in all pages. You can read more about the z-index spec here.
UPDATE - To also push the content down while using absolute positioning:
As you are already using a custom class to toggle the menu links, you can use that to also toggle the content section.
Add a selector rule as following to your stylesheet:
.menu-open~section#page {
transform: translateY(355px);
}
What this will do is, when the menu-open class is in the document, the sibling section with id of page, will be pushed down 355px.
You can also add a some kind of animation if you want a smoother effect on pushing the content down, like so:
#page {
margin-top: 100px;
margin-bottom: 100px;
opacity: 1;
position: relative;
transition: transform .3s linear;
}
I just added the transition, where the .3s is the time that the transition will take.
One problem with using absolute positioning, even if you use transforms to compensate for it, is that on some devices and browser widths, the logo will overlap the navigation. Observe what the current solution renders:
Another problem is the delay between when the navigation collapses and when the text is no longer visible:
Because this is Squarespace and you don't have access to edit the underlying DOM, I would use flexbox to solve this. To do that, first get rid of this:
#mobileNav {
background: none;
position: absolute;
top: 20%;
left: 0;
right: 0;
z-index: 1;
}
And add this:
#media only screen and (max-width: 640px) {
#canvas {
display: flex;
flex-direction: column;
}
#mobileMenuLink {
order: 1;
}
#mobileNav {
order: 2;
}
#header {
order: 3;
}
#header ~ * {
order: 4;
}
}
Note that the above is not vendor-prefixed, so if you want to support older browsers, you'd correspondingly want to add vendor prefixing.

Reset CSS hover dropdown with JQLite

I'm currently in a project developing an Angular SPA that has dropdown menus in its main navbar. To get this effect, we are using CSS: hover selectors. The issue is that when an action is performed within this dropdowns we would like to close them without hindering the ability to open them again. For example, if a user opens a link within one of this dropdowns (internal link with ui-sref) he is then taken to this particular state, but the dropdown would still be visible until he moves the mouse outside it (and partially obscuring the new content shown). We would like the dropdown to be closed when an action within is performed and if the user would like to open it again, he would be able to hover the mouse again over the trigger.
We tried removing and re-adding classes (even after a timeout) but the dropdown reappears again.
Link to a Plunker with a setup similar to what we are trying to accomplish: https://plnkr.co/edit/qzQk4r2WQFhwsgUWug39?p=preview
And the relevant portions (Angular controller omitted as it has no content):
HTML:
<div class="hoverable has-dropdown">
<button class="dropdown-trigger">Hover me!</button>
<div class="dropdown">
Dropdown content
<button ng-click="buttonAction()">Action</button>
</div>
</div>
CSS:
.dropdown {
display: none;
position: absolute;
top: 20px;
width: 100px;
height: 100px;
background: lightgrey;
padding: 1em;
}
.has-dropdown {
position: relative;
height: 20px;
}
.has-dropdown .dropdown-trigger:hover + .dropdown,
.has-dropdown .dropdown-trigger + .dropdown:hover {
display: block;
}
Thanks!
Finally solved it by using ng-mousenter and ng-mouseleave and dropping CSS :hover rules. As everything is based on JS I can just trigger mouseleave when I want to close them.

Use Only CSS to Alter Various Elements

I have a page with a left sidebar that I want to be able to toggle on or off based on whether or not the user clicks it. Unfortunately entering JavaScript code on this website has been disabled and I only have access to CSS.
The left sidebar has
its main div (parentBlock)
a div for the show/hide, (toggleBlock)
a div for the logo, (div1)
a div for the navbar, and (div2)
a div for social icons (div2)
When the user clicks on "Show / Hide" I want to:
Hide (display:none) the logo, navbar, and social div's, and
Set the height of the main div to something smaller (say 30px).
Is there any way to do this in CSS?
<div class="parentBlock">
<div class="toggleBlock">Show / Hide</div>
<div class="divBlah">div1</div>
<div class="divBlah">div2</div>
<div class="divBlah">div3</div>
</div>
Then if the user clicks "Show / Hide" again, it will unhide the div's and set the height back to filling the screen.
Is this possible?
I found some code that would work if the "Show / Hide" button was in "parentBlock" but it didn't work if it was within "toggleBlock" (and I have to have the Show/Hide button in toggleBlock)
(http://tympanus.net/codrops/2012/12/17/css-click-events/)
I realize onClick events require JavaScript. Those are not possible since I can't use JavaScript :( Some people try to get around it by using either :active or creating checkboxes and having the checkbox:clicked value load the action ... but it only works with certain relations that I can't seem to nail down.
Unfortunately I cannot alter the ultimate structure of "toggleBlock", div1, div2, and div3 ... only what's in them and their CSS. Also making it even more difficult is that the website randomly generates ID="" each time the page loads so the TARGET method isn't possible. Also, the 3 div's (div1 thru div3) have the same class name. I'm beginning to think it's impossible :(
(For reference, I'm trying to use the tools on the New SmugMug and they're rather restrictive)
Here is a CSS only solution using target
DEMO http://jsfiddle.net/kevinPHPkevin/r4AQd/
.button {
display: block;
width:60px;
background: red;
z-index:1;
}
#element {
display: none;
background:#fff;
margin-top:-20px;
z-index:2;
}
#element:target {
display: block;
}
#show:target {
display: block;
}
#hide {
background: #000;
color: #fff;
}
As Joum has pointed out this is not possible to do via click events but using hover on siblings you might be able to achieve a similar effect. for example try adding this css:
div.toggleBlock { display: block; }
div.toggleBlock ~ div { display: none; }
div.toggleBlock:hover ~ div { display: block; }

Is it possible to show a div on click using the :active selector in CSS?

I'm looking to show a div on click. The goal is to use pure CSS only, no jQuery.
Working FIDDLE Demo
Consider that you want something like this:
We write our markup as simple as possible. One element for container, one element for our link and one another element for popup:
<!-- [container] -->
<div class="link-with-popup">
<!-- link -->
<div class="link">CSS</div>
<!-- [popup] -->
<div class="popup">
<div class="box">CSS Description</div>
</div>
<!-- [/popup] -->
</div>
<!-- [/container] -->
Here is our layer structure in picture:
CONTAINER
Let's write CSS for our container.
.link-with-popup {
/* for visualizing */
background: yellow;
/* we need relative, because childs are absolute */
position: relative;
margin-bottom: 10px;
height: 30px;
width: 400px;
}
[!] Note that we make our container relative. Because the children will be in absolute mode.
LINK
We create our link as an absolute element from left, just as shown in the figure above.
.link {
background: blue;
position: absolute;
top: 0;
left: 0;
bottom: 0;
width: 100px;
z-index: 10;
}
POPUP
The dimention of popup element is same as the container, so we set all top, left, right, bottom properties to 0.
.popup {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
background: green;
z-index: 20;
}
[!] Note that z-index of popup element must be greater than link element.
.popup {
/* we won't show the popup yet */
display: none;
}
By now, we'll get this result (check it on jsFiddle):
Now we want the click for our link. This must be done with :active pseudo selector in CSS. But how we must show the poup? We have to get the next sibling element by the link. We use the + selector in CSS:
.link:active + .popup {
display: block;
}
See the result on jsFiddle. But the problem is that when user realize the mouse, the popup will disappear (as it display is set to none).
So we set the :hover rule for the popup and make it block.
.popup:hover {
display: block;
}
Check the jsFiddle demo. Now we get close enough. The only issue that the popup element, hide our link.
But it doesn't matter, because we won't set background for our popup (it will be transparent).
TEXT
For wanted text in popup element, we set this rules:
.popup .box {
position: absolute;
/* note that we make a gap from left to don't hide the link */
left: 130px;
top: 0;
right: 0;
bottom: 0;
background: #505050;
}
Check the jsFiddle demo. Now we have all things that we need.
Now it's time to make our popup element transparent (by setting the background as transparent or simply remove the background: green; rule):
.popup {
background: transparent;
}
And here is the final jsFiddle result. And if you add some extra CSS to it, it can be more stylish. Something like this that I've created.
Some important note to memorize:
In the final result, there is a gap between the link (blue one) and the popup (gray one). But the fact is that the gray element is not our popup. It's a child of popup and our popup is an 100% width and height element on the container.
Working FIDDLE Demo
Another way is to use the :target property (only works in moderns browsers).
Here's a qucik DEMO where I've hidden the div by applying opacity: 0; and the when you click the link the div changes to opacity: 1; The link and the div are matched using a hash in the url.
Here's the code from my example.
HTML
Click me
<br />
<div id="pop"></div>
CSS
#pop {
width: 100px;
height: 100px;
background: #000;
opacity: 0;
}
#pop:target {
opacity: 1;
}
There are some side effects though. The browser will jump/scroll down (not sure if it's possible to prevent this?) to the matched div and since we are using a hash in the url it will effect the browser history and, as mentioned above, it only works in modern browsers.
