Set up responsive sketched borders using css - html

I have created a code for setting up sketch style borders over image.
Which can be seen below:
jQuery('.border').click(function(){
jQuery('.border').toggleClass('resize');
});
body {
background-color: lightblue;
}
.border {
width: 200px;
margin: 0px auto;
position: relative;
-webkit-transition: all 2s;
/* Safari */
transition: all 2s;
background-image: url(https://nosycrow.com/wp-content/themes/nosy-crow/images/borders/black-400-sides.png);
background-repeat: repeat-y;
background-size: 100%;
border-radius: 15px;
background-position: 0 0;
padding: 5px;
overflow: hidden;
}
.border .padding::before, .border .padding::after {
content: '';
display: block;
position: absolute;
left: 0;
width: 100%;
height: 0;
background: url(https://nosycrow.com/wp-content/themes/nosy-crow/images/borders/black-400.png) no-repeat;
background-size: 100%;
z-index: 50;
padding-bottom: 5.4%;
pointer-events: none;
}
.border .padding::before {
top: 0px;
}
.border .padding::after {
bottom: 0px;
background-position: 0px 100%;
}
.border.resize {
width: 500px;
}
img {
width: 100%;
height: auto;
position: relative;
border-radius: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="border">
<div class="padding">
<img src="https://nosycrow.com/wp-content/uploads/imported-books/Spectre-Collectors-Too-Ghoul-For-School-312087-3-593x911.jpg" alt="">
</div>
</div>
But the issue is, the box is not accurately responsive. To test it out, I have added a little jquery script so when you click on the image, the image resizes. And you can see when the image is bigger, the borders doesn't look aligned properly.
I know in my solution, to fix this I have to add media queries so the borders on top and borders can be adjusted in media queries. But is there any better solution then that?

I got it fixed using different solution. Kind of old school. I used 3 images, horizontal line, vertical line and corner and used them to set up in their position using different divs. Can be seen here
jQuery('.sketchy-box').click(function(){
jQuery('.sketchy-box').toggleClass('resize');
});

You can use negative margin for last and first one to hide half the element:
.container {
display: flex;
height: 150px;
margin: 0 30px;
overflow:hidden;
}
.box {
flex: 1;
border: 1px solid;
transform: skew(-25deg);
position: relative;
overflow: hidden;
}
.box:first-child {
margin-left:calc((100% / 5) / -2);
}
.box:last-child {
margin-right:calc((100% / 5) / -2);
}
.box:after {
content: "";
position: absolute;
top: 0;
bottom: 0;
left: -50%;
right: -50%;
transform: skew(25deg);
background-image: var(--i);

Animated element not visible outside of parent container in Firefox

I have a animated div that flies to the top right corner of the viewport.
However, because of the overflow properties it not visible outside of parent container in Firefox. It is perfectly visible in Chrome.
Element behind the scrollbar in Firefox:
Element correctly above the parent in Chrome:
How can I make it work in Firefox as well? If overflow-y: auto is removed from .container the issue doesn't appear anymore, but that's not a viable solution as I need the scrollable content.
Here is an example. You can check that it produces the desired behaviour in Chrome, but not in Firefox:
.app {
overflow: hidden;
}
.container {
width: 260px;
max-height: 400px;
background: blue;
left: 10px;
right: 10px;
top: 10px;
position: fixed;
z-index: 500;
overflow-y: auto;
}
.wrapper {
height: 250px;
padding: 10px;
margin: 5px;
background: yellow;
top: 5px;
position: sticky;
}
.content {
height: 600px;
margin: 5px;
background: orange;
}

}
100% {

right: 160px;

}
}

Try this splution:
.wrapper position set to fixed
.content is shifted down with transform: translateY()
In the .wrapper class, i was add pointer-events: none;, because
if cursor is on the .wrapper block without this property, mouse
wheel cann't scroll the content, scroll work only when drag the
scroll bar.
.app {
overflow: hidden;
}
.container {
width: 260px;
max-height: 400px;

left: 10px;
right: 10px;
top: 10px;
position: fixed;
z-index: 500;
overflow-y: auto;
}
.wrapper {
display: flex;
height: 250px;
padding: 10px;
margin: 5px;
background: yellow;
/* top: 5px; */
position: fixed; /* changed */
/* calculate '.container' width - scroll-track-width(12px-17px) - '.wrapper' padding(left, right) - margin(left, right) */
width: calc(260px - 12px - 20px - 10px);
z-index: 5;
pointer-events: none; /* mouse wheel work with this property */
}
.content {
height: 600px;
margin: 5px;
background: orange;
/* calculate '.wrapper' properties to shift '.content' down */
/* height + padding(top, bottom) + margin-bottom */
transform: translateY(calc(250px + 20px + 5px));
}
#keyframes fly-to-top {

Edited after comment:
You can take the animated element out of its parent (i.e. the element which has overflow: hidden), on a higher level in the HTML code - as a sibling to the container. I did that in the snippet below, and also added a z-index that places the animated element above the container:
.app {
overflow: hidden;
}
.container {
width: 260px;
max-height: 400px;
background: blue;
left: 10px;
right: 10px;
top: 10px;
position: fixed;
z-index: 500;
overflow-y: auto;
}
.wrapper {
height: 250px;
padding: 10px;
margin: 5px;
background: yellow;
top: 5px;
position: sticky;
}
.content {
height: 600px;
margin: 5px;
background: orange;
}

Limit hover area of CSS shapes to :after

I am trying to make a sort of Venn-Diagram that is going to be used for navigation later.
I have three intersecting ellipsoids created with CSS shapes. Each ellipsoid, as well as their two intersections, will be distinct links later on. Also, when you hover over them they should pop out as per transform: scale(1.3).
My issue is that I'm using ellipsoids which are partially transparent with :after to create the intersections, which creates a problem when hovering over them because the :hover condition gets triggered when hovering anywhere on the partially transparent ellipsoid and not just the :after part. This means that the nonintersecting areas are not hoverable because they are obstructed by the other invisible ellipsoid.
I think the example will make this clearer.
Here is the code:
CSS:
.venn-container{position: relative; left: 0;}
.cat_one{
width: 400px;
height: 200px;

HTML:
<div class="venn-container">
<div class="cat_one"></div>
<div class="cat_two"></div>
<div class="cat_three"></div>
<div class="int1"></div>
<div class="int2"></div>
</div>
And here is a fiddle: https://jsfiddle.net/y3Lvmuqg/2/
I would like the :hover to only get triggered in the intersections, and later make cat_one and cat_two hoverable outside the intersections.
I don't know if there is a way I'm doing this is the best and I'm open to suggestions.
Thanks for getting back to me #ge0rg I spent about an hour fiddling with CSS and HTML and came up with this code using just divs with background colors, hover events and border radius's (along with a few z-index and positioning techniques).
Hope you enjoy your reworked venn diagram...
You may have to mess around with the size, and definetly will have to mess with the positioning (however they're all inside a div and so it makes it so that you can just position the div and the rest will happen magically) I added a background color to the div just to show that nothing was transparent, and I also added a always on top function for viewing a section, and I hope you enjoy!

Add triangle to top of div with background image in CSS

I'm trying to add a point/triangle to my div with a background image but am struggling with how to create enough empty space.
Here's what I'm going for:
Here's what I have so far:
<div class="bg"></div>
.bg {
position: relative;
background: url('http://i.imgur.com/W27LCzB.jpg');
background-size: cover;
width: 100%;
padding-top: 50px;
height: 200px;
}
.bg:before {
content:'';
border-left: 50px solid #fff;
border-right: 50px solid #fff;
border-bottom: 50px solid transparent;
position:absolute;
top: 0;
left: 0;
right: 0;
margin: 0 auto;
width: 0;
}
I tried following this Stack Overflow question, but the approach in the top answer creates borders that come from the ends of the rectangular div.
Could achieve your design using another div. Hope you'll like it :)
.bg {
position: relative;
background: url('http://i.imgur.com/W27LCzB.jpg');
background-size: cover;
width: 100%;
padding-top: 50px;
height: 200px;
}
.bg:before {
content:'';
border-left: 50px solid #fff;
border-right: 50px solid #fff;
border-bottom: 50px solid transparent;
position:absolute;
top: 0;
left: 0;
right: 0;
margin: 0 auto;
width: 0;
}
.helper {
position: absolute;
height: 50px;
top: 0;
left: 0;
right: 0;
}
.helper:before, .helper:after {
content: "";
background: white;
position: absolute;
top: 0;
bottom: 0;
width: calc(50% - 50px);
}
.helper:before {left: 0;}
.helper:after {right: 0;}
<div class="bg">
<div class="helper"></div>
</div>
You can achieve what you want by using pseudo element and skew them to get the shape border
.bg {
position: relative;
background: url('http://i.imgur.com/W27LCzB.jpg');
background-size: cover;
width: 100%;
padding-top: 50px;
height: 200px;
overflow: hidden;
}
.bg:before {
content: '';
background: #fff;
position: absolute;
top: 0;
right: calc(50% + 20px);
width: 150%;
height: 50px;
transform: skewX(-40deg);
}
.bg:after {
content: '';
background: #fff;
position: absolute;
top: 0%;
left: calc(50% + 20px);
width: 150%;
height: 50px;
transform: skewX(40deg);
}
<div class="bg"></div>
