How to set background to overlay text in next js?

I am creating an image element with overlay text. Here is my jsx code
<div className={styles.img}>
<img src={src} alt="" />
<p>{`(${size})`}</p>
</div>
and here is sass
.img {
min-width: 180px;
text-align: center;
cursor: pointer;
img {
height: 90px;
box-shadow: orangered 0 0 5px;
}
p {
color: white;
font-weight: bold;
margin: auto;
font-size: .8rem;
margin-top: - 1.6rem;
// max-width: 120px;
// z-index: 100;
background-color: #0070f3;
}
}
I get result as shown in following image. The background of p tag is visible only outside the img and not over the img.

How do I show the background for overlay text on image so that it is readable?

You need to set the position to something other than the default value (static) in order to use z-index. Here's an example with position: relative.
p
{
background: #0cf;
margin-top: -1.6rem;
z-index: 100;
}
p.positioned
{
position: relative;
}
<img src="http://via.placeholder.com/100x80"/>
<p>Test without positioning</p>
<img src="http://via.placeholder.com/100x80"/>
<p class="positioned">Test with positioning</p>

Thanks to comment by #Devid.
Just to clarify, the position: relative should be added on the p tag. Adding position: relative to the container div does not make any difference.

Z-Index of Material Dropdown component not layering underneath a fixed div when opened

Objective:
I would like the Header, Tab Section, and the Radio Button Section to be fixed in a form (see image below). Meaning that they should always be in view, and never have any overlapping elements.
The form looks like the following:
This is working fine when I simply scroll down on the form:
The Problem:
When I open the Angular Material dropdown, it overlaps over the Radio Button Section:
Here is the HTML. The highlighted sections are the elements that I want to be fixated on the form:
And here is the CSS for the 3 sections
//Header:
.module__header {
position: fixed;
top: 0px;
z-index: 1001;
display: flex;
height: 35px;
width: 100%;
background-color: #082749;
color: #FFFFFF;
font-size: 14px;
font-weight: 500;
align-items: center;
justify-content: stretch;
padding: 0;
margin-bottom: 0;
}
// Tab Section:
.mat-tab-label-container {
position: fixed;
top: 35px;
padding-top: 10px;
z-index: 1001;
width: 100%;
background: #fff;
}
// Radio Button Section:
.timaticFullTextView {
padding-top: 35px;
padding-left: 15px;
padding-bottom: 15px;
background: #fff;
z-index: 1001;
position: fixed;
width: 100%;
border-bottom: 1.5px solid gray;
}
I have tried changing the cdk-overlay-container to a z-index of <1001, but that still is overlapping the Radio Button Section.
How can I have the opened dropdown display underneath all 3 sections?
Edit: Adding screenshot to show the cdk-overlay that is giving issues. I have tried removing and lowering the z-index, but it doesn't have any effect

The problem is that mat-tab-body has z-index: 1 and this won't allow your fixed view inside to have a higher elevation. You can remove the z-index from mat-tab-body put then your content without a z-index won't be clickable anymore so you have to add a z-index and position to your not fixed content.
The code would have to look something like this:
<mat-tab>
<mat-tab-body> <!-- <-- added automatically -->
<div class="tab-header"></div>
<div class="tab-content"></div>
</mat-tab-body>
</mat-tab>
::ng-deep mat-tab-body {
z-index: unset !important;
}
.tab-header {
position: fixed;
z-index: 1001;
}
.tab-content {
position: relative;
z-index: 1;
}

You've found the right element whilst applying styles to the wrong one.
Here is how I made it work
.cdk-global-overlay-wrapper, .cdk-overlay-container {
z-index: 99999 !important;
}

Disable Anchor Within Hover Div on Mobile Until Open

I've searched high and low but can't find a solution to this exact problem.
On a desktop browser, when the user hovers over an image, a div appears and they can click the link within the div if they want. However, on a mobile device, the hover is triggered by a click. If the user clicks in just the right spot, even though the div isn't visible yet, they can accidentally click the anchor and navigate away from the page. (In other words, the div goes from display:none to display:block at the same time that the link is clicked.)
I want to prevent that accidental click from happening on mobile browsers, however I still want the link to be usable once the div is visible.
My code:
<style>
.staffpic {
position: relative;
width: 33.33333%;
height: auto;
}
.staffpic:hover .popup {
display: block;
}
.staffpic img {
display: block;
width: 110px;
height: 110px;
margin: 0 auto;
}
.popup {
display:none;
position: absolute;
bottom: 0;
left: -5px;
width: 100%;
height: 100%;
box-sizing: border-box;
padding: 15px;
background-color: rgba(255, 153, 0, 0.9);
color: #fff;
text-transform: uppercase;
}
</style>
<div class="staffpic">
<img src="/wp-content/uploads/image.jpg" />
<div class="popup">
John Smith, Director<br/>
CityName | Email John
</div>
</div>
Any ideas? HTML, CSS, JS and jQuery solutions are all welcome! (Maybe something more clever than what I can think of using pointer-events:none along with some jQuery?)

I'm actually about to encounter the same problem in a project, and jotted down a potential solution. Haven't tested it yet but it might help you out. The link should only trigger if the element has a display that's not 'none':
var popup = $('.popup'),
display = popup.css('display');
if (!(display === 'none')) {
popup.on('click', function(e) {
e.preventDefault();
});
}

I found a solution but it's not elegant. I wanted to post it in case someone has this problem in the future and just needs something that will work!
I added a fake link in a span with the real link then set new display styles for it and the real link based on the parent span is being hovered over.
<style>
.staffpic {
position: relative;
width: 33.33333%;
height: auto;
}
.staffpic:hover .popup {
display: block;
}
.staffpic img {
display: block;
width: 110px;
height: 110px;
margin: 0 auto;
}
.staffpic a {
display: none; /* Added */
}
.staffpic.link:hover a {
display: inline; /* Added */
}
.staffpic.link:hover .fakelink {
display: none; /* Added */
}
.popup {
display:none;
position: absolute;
bottom: 0;
left: -5px;
width: 100%;
height: 100%;
box-sizing: border-box;
padding: 15px;
background-color: rgba(255, 153, 0, 0.9);
color: #fff;
text-transform: uppercase;
}
</style>
<div class="staffpic">
<img src="/wp-content/uploads/image.jpg" />
<div class="popup">
John Smith, Director<br/>
CityName | <span class="link">Email John<span class="fakelink">Email John</span></span>
</div>
</div>
I'd still love a cleaner solution without all this added html if someone has it.

How to show/hide div with javascript?

So I want to hide a div for user settings, which shows when the user clicks on a little cog icon. What is the best way for me to go about this?
I made a couple of very basic pics to show what I'm after:
Closed:
Open:
Once the user clicks the icon (the red dot) then I want the hidden div to push the content to its right over. I had a look at the CSS checkbox hack, but that requires the user to click directly on the icon (the red dot) again to close the hidden div. I would like to have it so the user can click anywhere else on the page to close the div.
Anyone know how to do this with pure js?
Any help is greatly appreciated, thanks!

You can try tabindex="-1" in order to use :focus.
This way you can achieve it with pure CSS.
#wrapper {
display: flex;
position: fixed;
top: 0; right: 0; bottom: 0; left: 0;
}
#sidebar, #main, #hidden:focus {
padding: 10px;
}
#sidebar {
background: #A8D4AF;
}
#main {
flex-grow: 1;
background: #96A7B1;
}
#hidden {
width: 0;
background: #008DD2;
}
#hidden:before {
content: '';
display: block;
background: red;
border-radius: 50%;
position: relative;
left: -40px; top: 40px; /* Position of the dot*/
width: 20px; height: 20px; /* Size of the dot */
margin-bottom: -20px; /* Same as height */
}
#hidden:focus:before {
display: none;
}
#hidden:focus {
width: auto;
}
<div id="wrapper">
<div id="sidebar">
Test content
</div>
<div id="hidden" tabindex="-1">
Hidden stuff
</div>
<div id="main">
Lorem ipsum dolor
</div>
</div>

How to open <select> when image is overlapped

I am trying to overlap an image in front of a HTML element, so that I can simulate having a different arrow icon. I successfully achieved that, however even though I am able to click on the "text" area of the selector, obviously nothing happens if I click on top of the custom image (since it sits on top of the and is unrelated to it). I need to make it work for IE10 only, although I tried in Chrome and doesn't work either.
I did some research and seems like attaching some JS to the image to open the selector options is hard, if not impossible, specially for IE. As a separate effort, I tried setting a lower z-index for the image node, so that the mouse click event would ignore the image and go straight to the node, but didn't work. I wanted to check if anybody would have another idea, or if it's actually impossible to achieve.
Here is the fiddle for my code. For simplicity, I have replaced the image URL for just background-color: red
Fiddle
Here is the full code:
<style type="text/css">
.styled-select {
width: 240px;
overflow: hidden;
position: relative;
}
.styled-select select {
width: 268px;
z-index: 5;
background-color: transparent;
}
.imageNode {
background-color: red;
position: absolute;
right: 0px;
top: 2px;
height: 32px;
width: 32px;
overflow: hidden;
z-index: 3;
}
</style>
<div class="styled-select">
<select>
<option>Here is the first option!!!!!!!!!!</option>
<option>The second option</option>
<option>Third option!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!</option>
</select>
<div class="imageNode"></div>
</div>

You can do it by CSS :after pseudo element
html
<div class="custom-select">
<select>
<option>a</option>
<option>b</option>
<option>c</option>
</select>
</div>
css
div.custom-select {
position: relative;
display: inline-block;
}
.custom-select select {
display: inline-block;
padding: 4px 3px 3px 5px;
margin: 0;
font: inherit;
outline:none; /* remove focus ring from Webkit */
line-height: 1.2;
background: #000;
color:white;
border:0;
}
/* Select arrow styling */
.custom-select:after {
content: "▼"; /* Current arrow I would like to change */
position: absolute;
top: 0;
right: 0;
bottom: 0;
font-size: 60%;
line-height: 30px;
padding: 0 7px;
background: #000;
color: white;
}
.no-pointer-events .custom-select:after {
content: none;
}
