Unblur content inside blurring background div - html

So I really like this kind of special effect here https://www.w3schools.com/howto/howto_css_blurred_background.asp where you can blur out a background and have the text show up. The problem that I am currently having right now is that I want to add in another wallpaper for my second content below my first content. The first content is good. Now I want my second content to be in the second wallpaper as you scroll. Kind of like creating a parallax effect, but instead I am am creating my own unique website.
This time I want a blurring background (wallpaper number two) while having the stuff where I already want it placed and have it focus.
Is there a way to achieve that?
Starting where the bg-image2, I want the h1, and the p, inside bg-image2 to focus over the blurring background image.
NOTE: The wallpaper will not show in the snippet below because I already got the pictures I need in my folder which is located in my computer.
body,
html {
height: 100%;

box-sizing: border-box;
}
.bg-image {
/* The image used */
background-image: url("images/wallpaper1.jpg");
/* Add the blur effect */
filter: blur(8px);

<div class="bg-text">

<p>And I am a website</p>
</div>
<div class="bg-image2">
<!-- This is the part where I want my stuff to not be blurred and focus -->
<div class="profilePicture">
<img src="images/profilePic.jpg" style="width: 170px; height: 170px; border-radius:50%;">
<h1>This is a title</h1>
<p>This is just a paragraph</p>
</div>
</div>

Is that the result you are looking for?

All i did was to create a div around the bg-image2 and profilePicture, so that the blur on bg-image2 doesn't affect profilePicture, then set that div to position:relative; , so that the profilePicture can be placed in the middle like you did.
Here is your HTML edited:
<div class="bg-image"></div>
<div class="bg-text">
<h1>My name is Stackoverflow</h1>
<p>And I am a website</p>
</div>
<div class="bg-test">
<div class="bg-image2">
<!-- This is the part where I want my stuff to not be blurred and focus -->
</div>
<div class="profilePicture">

I was facing a similar issue. After a lot of searches, I found the perfect solution.
You can use backdrop-filter.
Your code:
body,
html {
height: 100%;
}
* {
padding: 0px;
margin: 0px;
box-sizing: border-box;
}
.bg-image {
/* The image used */
background-image: url("https://images.unsplash.com/photo-1507608616759-54f48f0af0ee?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&w=1000&q=80");
/* Add the blur effect */
/* Full height */
height: 100%;
/* Center and scale the image nicely */
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
/* Position text in the middle of the page/image */
.bg-test {
position:relative;
}
.bg-text {
background-color: rgb(0, 0, 0);
/* Fallback color */
background-color: rgba(0, 0, 0, 0.4);
/* Black w/opacity/see-through */
color: white;
font-weight: bold;
backdrop-filter: blur(8px);
border: 3px solid #f1f1f1;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
z-index: 2;

padding: 20px;
text-align: center;
}
.bg-image2 {
/* The image used */
background-image: url("https://blog.prezi.com/wp-content/uploads/2019/03/patrick-tomasso-208114-unsplash-1024x768.jpg");
/* Add the blur effect */

height: 100vh;
/* Center and scale the image nicely */
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
.profilePicture {
backdrop-filter: blur(8px);
height: 100vh;
width: 100vw;
display: flex;
flex-direction: column;

align-items: center;
position: absolute;
left: 50%;

How to place text to the left of the background image and adapt it to phones

I need the text to be
text-align:center , but as soon as I write it, the text moves to the center, and I need it to be on the left and I need to adapt it to phone screens.
I tried via #media but nothing worked.
my css code
position: absolute;
left: 0;
top: calc(50% - 2rem);
transform: translateY(-50%);
padding-left: 12px;
margin-top: 0;
z-index: 2;
background: none;
border-radius: .25rem;
width: 100%;
order: 2;
color: white;
bg-image {
/* The image used */
background-image: url("img/ob.jpg");
/* Full height */
height: 90%;
/* Add the blur effect */
filter: blur(4px);
-webkit-filter: blur(4px);
/* Center and scale the image nicely */
background-position: unset;
background-repeat: no-repeat;
background-size: cover;
}
my html code
<section class="bg-text">
<h1>ffff</h1>
</section>
You can use the Image overlay method inside of the picture with text.
<div class="container">
<img src="img_snow_wide.jpg" alt="Snow" style="width:100%;">
<div class="bottom-left">Bottom Left</div>
<div class="top-left">Top Left</div>
<div class="top-right">Top Right</div>
<div class="bottom-right">Bottom Right</div>
<div class="centered">Centered</div>
</div>
/* Container holding the image and the text */
.container {
position: relative;
text-align: center;
color: white;
}
/* Bottom left text */
.bottom-left {
position: absolute;
bottom: 8px;
left: 16px;
}
/* Top left text */
.top-left {
position: absolute;
top: 8px;
left: 16px;
}
/* Top right text */
.top-right {
position: absolute;
top: 8px;
right: 16px;
}
/* Bottom right text */
.bottom-right {
position: absolute;
bottom: 8px;
right: 16px;
}
/* Centered text */
.centered {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
OR
Simply you can use the CSS shape-outside Property to wrap the text with an image.
The shape-outside Property comes with values,
shape-outside: none |<shape-box&gt> | <basic-shape> | <image> | initial | inherit

Flip box image not displaying correctly when responsive

I am using Vue (not that it matters as this is a CSS issue I'm sure).
I have 3 flip boxes, taken mostly from the w3schools instructions at https://www.w3schools.com/howto/howto_css_flip_box.asp and all works as expected on a Desktop screen.
However, on my phone the image doesn't fit the whole box, leaving a space at the bottom. I have added background-repeat: no-repeat; as otherwise the image starts to repeat to fill in the space
Edit: Adding the html as requested ion the comments:
<template>
<div class="flip-box">
<div class="flip-box-inner">
<div class="flip-box-front">
<h2>{{ frontText }}</h2>
</div>
<div class="flip-box-back">
<div class="opaque-box">
<p class="mt-3 ms-2">{{ backText }}</p>
<span v-html="url"></span>
</div>
</div>
</div>
</div>
</template>
Is there anything obvious from the css below?
Thanks
<style scoped>
body {
font-family: Arial, Helvetica, sans-serif;
}
.flip-box {
width: 300px;
height: 200px; /* 200 best for desktop but not mobile */
border: 1px solid #f1f1f1;
perspective: 1000px;
}
.flip-box-inner {
position: relative;
width: 100%;
height: 100%;
text-align: center;
transition: transform 0.8s;
transform-style: preserve-3d;
}
.flip-box:hover .flip-box-inner {
transform: rotateX(180deg);
object-fit: fill;
}
.flip-box-front, .flip-box-back {
background-image: v-bind(backgroundImage);
position: absolute;
width: 100%;
height: 100%;
color: white;
-webkit-backface-visibility: hidden;
backface-visibility: hidden;
}
.flip-box-front {
background-size: 100%;
background-repeat: no-repeat;
}
.flip-box-back {
background-size: 100%;
background-repeat: no-repeat;
font-weight: 600;
transform: rotateX(180deg);
}
.opaque-box{
position: absolute;
background-image: v-bind(backgroundImage);
background-size: 100%;
background: rgba(0, 0, 0, 0.50);
height: 100%;
}
</style>
Having spent quite some time wrestling with this before posting I have now fixed it by adding background-size: cover;
So the CSS now looks like this:
<style scoped>
...
.flip-box-front {
background-size: 100%;
background-repeat: no-repeat;
background-size: cover; /* Added this */
}
.flip-box-back {
background-size: 100%;
background-repeat: no-repeat;
font-weight: 600;
transform: rotateX(180deg);
background-size: cover; /* Added this */
}
...
</style>

How to Overlay Image on Background in Twitter Bootstrap Section

I have an image that I would like to overlay on top of a background gradient that I have set on a section element. Both the background gradient and image I am setting in CSS and calling via a class in HTML. Originally when just using the background gradient it worked fine, but after adding the image to place over the background gradient the background gradient disappeared?
.banner-gradient {
background: radial-gradient(circle, #ba000b, #9e0008);
color: white;
z-index: 0;
}
.banner-overlay {
background: url("../imagery/image.png");
max-width: 100%;
height: auto;
background-position: bottom;
background-repeat: repeat-x;
z-index: 1;
}
.section-align-center {
text-align: center;
}
<section class="banner-gradient banner-overlay section-align-center">
<div class="container">
<p>image over background gradient</p>
</div>
</section>
Try using background-image instead of background for image.
.banner-gradient:before {
content: " ";
width: 100%;
height: 100%;
position: absolute;
z-index: 1;
top: 0;
left: 0;
background: -webkit-radial-gradient(top center, ellipse cover, rgba(255,255,255,0.2) 0%,rgba(0,0,0,0.5) 100%);
}
.banner-overlay {
background: url('https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png?v=c78bd457575a') repeat;
}
.section-align-center {
height: 400px;
position: relative;
}
<section class="banner-gradient banner-overlay section-align-center">
<div class="container">
<p>image over background gradient</p>
</div>
</section>
I solved this with the help of this post. You must first place the banner-gradient in your outer div then in your inner div use banner-image.
HTML
<section class="banner-gradient section-align-center">
<div class="container banner-overlay">
<p>image over background gradient</p>
</div>
I would rather edit the class of the element you want the transparency in
<div class="background">
<div class="transbox">
<p>This is some text that is placed in the transparent box.</p>
</div>
</div>
div.background {
background: url('https://www.w3schools.com/css/klematis.jpg') repeat;
border: 2px solid black;
}
div.transbox {
margin: 30px;
background-color: #ffffff;
border: 1px solid black;
opacity: 0.6;
filter: alpha(opacity=60); /* For IE8 and earlier */
}
div.transbox p {
margin: 5%;
font-weight: bold;
color: #000000;
}

Blurring Background image shrinks it, how to blur without it shrinking?

without blur . with blur
I'm a beginners for html,css. I'm trying to blur the background-images for each of my divs, but instead it shrinks it down. How do I go about blurring without it shrinking?
.parallax {

height: 100vh;
font-size: 200%;
overflow-x: hidden;
overflow-y: auto;
perspective: 300px;
perspective-origin-x: 100%;
}
.parallax .title {

background-image: url("image/bubble.png");
background-size:contain;
-webkit-filter: blur(5px);
filter: blur(5px);
height: 500px;
height: 100vh;
}
<div class="group group2">
<div class="layer base">

Use background-size: cover for .parallax .group2 .back. The background image will cover the whole div area.

Blurred portion over image, solid edges, responsive images

I'm trying to replicate the following blur effect with pure HTML/CSS. My current appraoch uses 2 images, the original cover-image, then, a 2nd copy of the image blurred-bg-image using CSS filter: blur(5px);.
Desired effect:
source
I can't find any way to keep the bottom portion the height of the toolbar while also retaining a background-image equal to the dimensions of the entire cover-image.
overflow: hidden doesn't work on a child element when the parent is anything but position: relative. But if the parent is relative, the inner blurred-bg-image is not the same dimensions as the cover-image
Here is the basic setup:
<div class="cover-image">
<div class="toolbar">
<div class="blurred-bg-image"></div>
</div>
</div>
The only solution I can find so far is to use clip rect() on blurred-bg-image, then calculate where to clip it to. But, this is not responsive and includes JS into the mix.
Here is a CodePen by the OP showing the end result.
The Method
You can use the method described here on CSS Tricks.
This method utilizes the following:
absolute positioning
transforms
one image for the background and blur effect
You'll have to adjust things with media queries, but that's not difficult. The only main drawback I see is that you have to set a fixed height on the toolbar content, because that height is used in the transforms. But again, that's easily done with media queries.
See the following snippet for the source and demo. I put some comments in the CSS.

-ms-filter: blur(5px);

}
.cropper {
overflow: hidden; /* performs the cropping */
}
/* apply to both .cropper and .glass */ /* enables crop from the top */
.flip {
-webkit-transform: rotate(180deg);
-moz-transform: rotate(180deg);
-ms-transform: rotate(180deg);
-o-transform: rotate(180deg);
transform: rotate(180deg);
}
Basically, we got two identical background images except one has a tint and blur effect, and is wrapped by an upside-down cropper.

I've added the background image to the toolbar using ::before, which is positioned at the top of the toolbar. The image area and the pseudo element height should use a root based units, such as vh or rem, so they will be the same size regardless of their container size. In addition, the pseudo element background settings are identical to those of the main background. The pseudo element is blurred, and excess background is removed using the toolbar's overflow: hidden.
Resize the results panel in this Fiddle demo.
html, body {
margin: 0;
padding: 0;
}
.top-image {
position: relative;
min-height: 100px;
}
.top-image, .toolbar::before {
height: 50vh; /** the image and the blurred area height **/
background: url('http://www.theplanningboardroom.net/wp-content/uploads/2011/06/sydney-city-buildings.jpg') no-repeat;
background-size: cover;
}
/** the .toolbar::before is position at the bottom of the toolbar, so excess height goes up **/
.toolbar, .toolbar::before {
position: absolute;
right: 0;
bottom: 0;
left: 0;
}
.toolbar {
z-index: 1;
/** height can also be percentage such as 20% **/
height: 100px;
/** hide the rest of the background ::before **/
overflow: hidden;
/** some styling for the text and controls **/
box-sizing: border-box;
padding: 10px;
text-align: center;
}
.toolbar::before {
z-index: -1;
display: block;
/** the height is full screen height **/
-webkit-filter: blur(5px);
filter: blur(5px);
content:'';
}
<div class="main">
<div class="top-image">
<div class="toolbar">

</div>

<div>
<p>The content</p>
</div>
</div>
If you don't wish the toolbar to be on the edge of the image, you can position it anywhere you wish inside it. Just set the toolbar's left, right, and bottom, and .toolbar::before properties the negative value (demo):
.toolbar {
position: absolute;
right: 100px;
bottom: 50px;
left: 100px;
}
.toolbar::before {
position: absolute;
right: -100px;
bottom: -50px;
left: -100px;
}
I don't know why you're getting problem in doing this, I was able to do it by using another div extending it fully wide and height equal to the toolbar and then set the same background-image and then blurred it.
Here is the code-
html,
body {
margin: 0;
padding: 0;
}
#container {
width: 100%;
background: black url('http://tinyurl.com/pgfnxag') bottom center no-repeat;
background-size: 100% auto;
position: relative;
overflow: hidden;
color: white;
font-size: 30px;
text-align: center;
}
#glass {
background-color: rgba(255, 255, 255, 0.25);
padding: 35px 0;
width: 100%;
color: white;
position: absolute;
bottom: 0;
border-top: 1px solid rgba(255, 255, 255, 0.2);
}
#blurred {
position: absolute;
width: 100%;
background: url('http://tinyurl.com/pgfnxag') bottom center no-repeat;
background-size: 100% auto;
filter: blur(5px);
-webkit-filter: blur(5px);
-moz-filter: blur(5px);
-o-filter: blur(5px);
-ms-filter: blur(5px);
top: 0;
left: 0;
height: 100%;
}
#content {
z-index: 999;
display: block;
position: absolute;
top: 50%;
left: 50%;
font-size: 20px;
font-weight: 100;
transform: translate(-50%, -50%);
font-family: Segoe UI;
text-align: center;
}
<div id="container">This is content above blurred part... Lorem ipsum dolor sit amet... and after that so more contents can go here..
<br />
<br />
<br />
<br />
<br />
<br />
<div id="glass">
<div id="blurred"></div>
<div id="content">Here goes the content..</div>
</div>
</div>
Fiddle demo to play with height of #glass and edit contents present in #content, the #blurred is the div holding the same background-image. The real trick here was to set all background properties (background-size, background-position, etc) exactly same as the #container.
UPDATE: changed to background-size: 100% auto;, now works well for any height or width of container or viewport.
EDIT: Removed all height properties, now its fully responsive! Run Code Snippet above.
Backdrop filters can do this, but are currently working only in Safari with the -webkit- prefix (and Chrome if you enable "Experimental Web Platform Features").
.toolbar{
-webkit-backdrop-filter: blur(5px);
backdrop-filter: blur(5px);
}
