css bootstrap full screen issue - html

I've been able to set a full screen background in my website. It looks like this:
The problem is when I make the window smaller. It looks like this:
And if i scroll down the site, the result is this ugly thing:
Do you know how could I solve this? I have the same issue when I try to see the site from a mobile:
Once the problem has been statedm let's see the code:
HTML:
<div class="slides fullscreen-bg fullscreen-bg__img text-center">
<p id="slide1" style="width: 100%; float: left; margin-right: -100%; opacity:1; ">
<img class="img-responsive" alt="Panoramic view from the window of one of the penthouses" src="~/Content/Images/Portada2.jpg" height: "auto">
</p>
<p id="slide2" style="width: 100%; float: left; margin-right: -100%; opacity:0; ">
<img class="img-responsive" alt="Panoramic view from the window of one of the penthouses" src="~/Content/Images/Portada.JPG">
</p>
</div>
CSS
.fullscreen-bg {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
overflow: hidden;
z-index: -100;
}
.fullscreen-bg__img {
position: absolute;
top: 0;
left: 0;
min-height: 100%;
width: 100%;
height: 100%;
color:#000;
-webkit-filter: brightness(0.5);
}
.img-responsive {
margin: 0 auto;
}
.logo {
position: relative;
margin-top: -15%;
}
I leave a link to the site in case you want to reproduce the errors yourselves:

EDIT

.slides p {
width: auto !important;
}
.slides p img {
min-height: 100%;
}
This isn't perfect. You get image distortion at very tall portrait aspect ratios. It would be better if your images were backgrounds on div elements.

please if you use as background. we have css3 property background-size: cover
or if you as html need to make from javascript.

Edit the pictures in a photoprogram (f.exam PhotoFiltre) And make the the two pictures into one.

contain image in 60%-height-div, while keeping aspect ratio

What I am trying to accomplish:
- create a pop-up div (fixed), centered in view
- this pop-up should be 60% height of the browser window
- the contents of the pop-up should be an image and a 'x' above the upper right corner of the image
- the height of the image should be maximal, considering it should be contained in the div together with the 'x'
- the aspect ratio of the image should be maintained
I tried the following code
<div class="pop-up">
<p class="exit-button">x</p>
<img class="image" src="safari.png" width="1200" height="630" alt="" title="" />
</div>
With CSS:
body {
background: #333;
}
.pop-up {
position: fixed;
height: 60%;
width: auto;
left:50%;
top:50%;
-webkit-transform:translate(-50%,-50%);
transform:translate(-50%,-50%);
background:yellow;
object-fit: contain;
}
.exit-button {
text-align: right;
margin: 0;
font-size: 300%;
}
.image {
height: 100%;
width: auto;
opacity:0.7;
}
This code is not solving the problem, the image is not contained in the (yellow) div, as can be seen in the following screen shot:
http://www.michielvisser.nl/tmp/screenshot.jpg
How to contain the image in the div with maximal height for the image in the div and maintain aspect ratio?
SOLUTION 1: Remove the height and width from .pop-up and change height:100% in .image to height:60vh. That works perfectly. Apparently the child (img) will not adjust to the parent (div), but the parent (div) will adjust to the child (img). Sounds like real life.
SOLUTION 2: Essentially the problem arises when the window is resized (except in firefox). The solution can be to redraw the image after a resize, this solves the problem:
$(window).resize(function(){
$('img').hide();
setTimeout(function(){ $('img').show(); }, 1);
});
Your problems are:
You have an inline width and height set on your image, which is overriding the CSS styles for width and height on that image
The margin from your X is pushing the image down since the X is wrapped in a <p> tag.
You don't need object-fit at all.
The simple way to solve #1 is to delete the inline width and height from the image tag and leave it to the stylesheet.
Number 2 can be solved by wrapping the X in a div instead of a p, or you can use a pseudo element for it. I have taken the latter approach in the snippet below.
To solve #3, just delete the style from the stylesheet. (Having this property set in Safari actually messed things up for me.)
This snippet is tested in Safari 10.1.1. Note how the placeholder image is quite large by default (1000x800), but it only displays as big as it can per the parent div.
Edit: Based on your comments, let's revise this further so that we dictate the size on the image, and just let the wrapper take up the size of the image.
So on our image, in order to get it to be 60% as tall as the screen, we can do:
img {
height: 60vh;
width: auto;
}
Then, in our parent, we won't specify a width or height at all, but we can do display: flex just to make sure it is big enough to fit its contents.
body {
background: #333;
}
.pop-up {
display: flex;
position: fixed;
left: 50%;
top: 50%;
-webkit-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
background: yellow;
}
.exit {
color: black;
text-decoration: none;
text-align: center;
font-size: 300%;
display: block;
position: absolute;
top: -50px;
right: -40px;
width: 40px;
height: 50px;
}
.image {
height: 60vh;
width: auto;
opacity: 0.7;
}
<div class="pop-up">
X
<img class="image" src="http://placehold.it/1000x800" alt="" title="">
</div>
I put the image above the P tag and added some CSS to .exit-button and .image
From here you can adjust padding and sizing of the elements.
body {
background: #333;
}
.pop-up {
position: fixed;
height: 60%;
width: auto;
left:50%;
top:50%;
-webkit-transform:translate(-50%,-50%);
transform:translate(-50%,-50%);
background:yellow;
object-fit: contain;
}
.exit-button {
position: absolute;
text-align: right;
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: 0;
font-size: 300%;
}
.image {
height: 100%;
width: auto;
opacity:0.7;
}
<div class="pop-up">
<img class="image" src="http://icons.iconarchive.com/icons/johanchalibert/mac-osx-yosemite/1024/safari-icon.png" width="1200" height="630" alt="" title="" />
<p class="exit-button">x</p>
</div>
I copied your code and edited it. Please tell me whether this is the output you wanted or not.
body {
background: #333;
}
.pop-up {
position: fixed;
height: 60%;
width: auto;
left:50%;
top:50%;
padding-top: 30px;
-webkit-transform:translate(-50%,-50%);
transform:translate(-50%,-50%);
background:yellow;
object-fit: contain;
}
.exit-button {
margin-top: -50px;
text-align: right;
margin-right: 0;
font-size: 300%;
}
.image {
margin-top: -20px;
height: 100%;

opacity:0.7;
}
<div class="pop-up">
<p class="exit-button">x</p>
<img class="image" src="safari.png" alt="" title="" />
</div>
Because of either needing to hardcode in the alignment of the image given the size or deal with weird convolution, I believe this is the best way:
Create a fixed overlay occupying the entirety of the screen, create a container of 60% height, align it in the center with flexbox and stick the image inside making it occupy the entire height. The aspect ratio will update automatically (only happens with height).
As for the button – give it absolute positioning and a right position of 0, and manually give the parent relative positioning (this is necessary).

}
a {

I believe that's the least amount of convolution if you want it to be dynamic.

Make opacity of div on sides

I recently have created this banner for my website, but I realized that I only want the main part of my site to be 900px long. However, I want the banner to run off the page, but have the part where it runs off be darkened (through opacity). So, this means, I need to make the image of my site positioned in the middle. Here is what I developed so far:
https://jsfiddle.net/h3w89t9y/4/
As you can see, this doesn't really get what I need. Here's the issue:
.banner {
background:url(https://i.gyazo.com/74f0fa6b9d9ed6652f3e220ceae113cf.png) no-repeat;
background-position: center;
margin: 0 auto;
height:185px;
}
The banner isn't 800px. If I add in a width of 800px, it will go to the middle just like I wanted. However, the image will be limited to only be 800px long rather than overflowing off of 800px.
This is what I'm trying to get it to look like:
https://i.gyazo.com/c38cae7bd34379477a6fcc8eeb160c22.png
How do I make it to where my banner is centered to the middle, but has the sides overlapped with opacities?
You can achieve what you want using pseudo like this:
body {
margin: 0;
}
.wrapper {
background:url(https://i.gyazo.com/74f0fa6b9d9ed6652f3e220ceae113cf.png) no-repeat center;
width: 100%;
}
.wrapper:before, .wrapper:after {
content:'';
width: calc((100% - 900px) / 2); /*setting the width to the 100% minus your desired header's width / 2 so it will occupy the rest of your content*/
height:185px;
position: absolute;
top: 0;
background: rgba(0, 0, 0, 0.3); /*set the desired opacity*/
}
.wrapper:before {
left: 0;
}
.wrapper:after {
right: 0;
}
.banner {
width: 900px;
height:185px;
margin: 0 auto;
}
<div class="wrapper" style="">
<div class="banner"></div>
</div>
So the idea is your pseudo elements occupy the rest of the content and setting them your desired transparency, notice that in this way you also can set them blur or whatever filter that you want.
Here a working jsfiddle to play with
You can't control opacity of a single background like that, you need another element. For example:
.banner, .bannert {
background:url(https://i.gyazo.com/74f0fa6b9d9ed6652f3e220ceae113cf.png) no-repeat;
background-position: center;
margin: 0 auto;
height:185px;
}
.banner {
max-width: 800px;
position: absolute;
left: 0;
right: 0;
top: 0;
}
.bannert {
background-repeat: repeat-x;
opacity: 0.5;
}
<div style="width: 100%; background: black; padding: 1px;position: relative;">
<div class="bannert"></div>
<div class="banner"></div>
</div>
https://jsfiddle.net/h3w89t9y/6/
Try this; add two divs first, one for the left side, and one for the right,hence you can apply your desired opacity to them and make the banner sides filtered, look at the snippets below;
HTML
<div style="width: 100%; padding: 1px;">
<div class="banner">
<div class="trans_right"></div>
<div class="trans_left"></div>
</div>
</div>
CSS
.trans_right {
padding: 2rem;
width: 13%;
float: right;
background: rgba(71,67,255,0.9);
height: 65%;
}
.trans_left {
padding: 2rem;
width: 13%;
float: left;
background: rgba(71,67,255,0.9);
height: 65%;
}
I'm really not sure if there is a better way to do this, but it gives you what you're looking for, checkout the link:

Stretch background image width but crop height

How do you make a background img that would:
Stretch across the window horizontally
Have a fixed height
Crop height when it's bigger than the content's height (do not shrink)
Currently I have this code that implements #1 and #2 but I can't seem to make it do #3:
<img class="background" src="images/page-background.png"/>
html {
position: relative;
}
.background {
width: 100%;
height: 2800px;
position: absolute;
top: 0;
left: 0;
z-index: -1;
}
I tried moving the img inside a div with overflow: hidden but that didn't work for some reason:
<div class="background-wrap">
<img class="background" src="images/page-background.png"/>
</div>
.background-wrap {
position: absolute;
width: 100%;
height: 1000px;
overflow: hidden;
z-index: -1;
}
How would you do this properly in CSS / HTML (without JavaScript)?
You could use a css background-image on a div like so:
.background-wrap {
background: url(images/page-background.png) no-repeat;
background-size: 100% 500px;
}
The background-size specifying that;
Stretch 100% across the window horizontally, and have a 500px fixed height (change this to auto if you want the image height to scale in proportion to the width).
Sorry guys, it turns out I completely forgot to remove a duplicate background <img> that I left after splitting my HTML in multiple files (actually PHP files but that's irrelevant).
For the sake of future reference, the following worked for me:
<html>
<head>...</head>
<body>
<div class="background-wrap">
<img class="background" src="images/page-background.png"/>
</div>
</body>
</html>
html {
position: relative;
}
.background-wrap {
position: absolute;
width: 100%;
top: 0;
bottom: 0;
overflow: hidden;
z-index: -1;
}
.background {
width: 100%;
height: 2800px;
position: absolute;
top: 0;
left: 0;
z-index: -1;
}

How can I highlight part of an image on a webpage?

I want to mask out part of an image on a page, making part of the image darker so a highlighted portion stands out. (This is often used to preview the effect of the crop tool in photo editors.)
Currently, my plan involves loading two copies of the images on top of each other and using clip: rect(); to slice out of a portion of the top image. Is there a better way to handle this? I should also mention that my image is actually an animated GIF (oh dear ...)
I thought it best to figure this out before I started trying to update the crop with javascript.
CSS:
.container {
width: 1075px;
margin: 10px;
border: 1px solid black;
padding: 10px;
overflow: auto;
}
.image-container {
position: relative;
clear: both;
background-color:#eee;
}
.background{
opacity:.40;
}
.highlight {
position: absolute;
top: 0px;
left: 0px;
clip: rect(126px 257px 197px 156px);
}
HTML:
<div class="container">
<div class="image-container">
<img class="background" src="animate.gif" width="1075" height="605" />
<img class="highlight" src="animate.gif" width="1075" height="605" />
</div>
</div>
Position the image using position: absolute for each image. The layer above should be smaller then the bottom one. Than use background-position: x y;
Something like this:
#image1, #image2 {
position: absolute;
left: 0;
top: 0;
background: url('https://www.google.com/intl/en_ALL/images/logos/images_logo_lg.gif')
}
#image1 {
min-width: 276px !important;
min-height 110px !important;
opacity: 0.5;
}
#image2 {
left: 251px;
width: 25px;
height: 110px;
background-position: 100% 100%;
}​
Look here an example:
http://jsfiddle.net/8n3Rr/
Try to position a <div> over the images, put a low opacity on it and a width or height half the size of the image.

CSS Working in Chrome but not Firefox ( div height )

I have been building a website and mainly testing it in Chrome.
Recently I realised some of the CSS does not apply in Firefox.
I guess it's probably : main { min-height }
This jFiddle reproduces this error, where the main div doesn't have the height it's supposed to. http://jsfiddle.net/msW9m/
HTML :
<div id='main'></div>
<div id="container"></div>
<div id='footer'>
<div id='footerRelative'>Development by <a href='mailto:'>John Doe</a></div>
</div>​
CSS :
#main {
min-height: 80%;
height: auto;
border: 1px solid #bbbbbb;
margin: 3% 5% 1%;
padding: 10px 10px;
}
#footer {
position: absolute;
left: 50%;
}
#footerRelative {
position: relative;
left: -50%;
font-size: 80%;
}
/*Probably Irrelevant*/
#container {
margin: 0 auto;
margin-top: -300px;
margin-left: -261px;
position: absolute;
top: 50%;
left: 50%;
width: 523px;
height: 600px;
background-image: url('../images/doctorSymbol.jpg');
background-repeat:no-repeat;
background-position:center;
opacity: 0.125;
overflow: hidden;
z-index: -1;
}
However, in Chrome everything works perfectly and the main div has a min-height of 80% . I was wondering if there is a workaround to this or If I am doing something wrong.
Thank you.
Have you tried making body and html 100%?
In some browsers, the body element doesn't keep 100% height until its content is full.
http://jsfiddle.net/HRKRN/
html, body {
height: 100%;
}
Also a possible solution that worked for me: set the div's display to table-cell.
