I saw this Interactive Particle Logo on Codepen and I would like to add something smaller to my site. However, I couldn't understand how can I change it and add my own logo. I believe I need to change what is inside the data-src in the index.html and #hintImg in the style.less and provide my logo. Still, I don't know how to do this it is not like the simple img src where I can just upload the photo from my PC or paste the URL.

You need to change the data in the div#first-slide block. The section data:image/png;base64, remains the same, but you need to replace the rest with a Base64-encoded version of your desired image.
To create the Base64 data, you can use one of the various websites that will do this for you - upload your image and you'll get the Base64 text to paste into your code. This is a random one I found with a quick search. I used it to grab a random PNG image, convert to Base64 and replace the text in the Codepen you provided - and it worked.
How can I hide the broken image icon?
Example:
I have an image with error src:
<img src="Error.src"/>
The solution must work in all browsers.
There is no way for CSS/HTML to know if the image is broken link, so you are going to have to use JavaScript no matter what
But here is a minimal method for either hiding the image, or replacing the source with a backup.
<img src="Error.src" onerror="this.style.display='none'"/>
or
<img src="Error.src" onerror="this.src='fallback-img.jpg'"/>
Update
You can apply this logic to multiple images at once by doing something like this:
document.addEventListener("DOMContentLoaded", function(event) {
document.querySelectorAll('img').forEach(function(img){
img.onerror = function(){this.style.display='none';};
})
});
<img src="error.src">
<img src="error.src">
<img src="error.src">
<img src="error.src">
Update 2
For a CSS option see michalzuber's answer below. You can't hide the entire image, but you change how the broken icon looks.
Despite what people are saying here, you don't need JavaScript at all, you don't even need CSS!
It's actually very doable and simple with HTML only.
You can even show a default image if an image doesn't load. Here's how...
This also works on all browsers, even as far back as IE8 (out of 250,000+ visitors to sites I hosted in September 2015, ZERO people used something worse than IE8, meaning this solution works for literally everything).
Step 1: Reference the image as an object instead of an img. When objects fail they don't show broken icons; they just do nothing. Starting with IE8, you can use object and img tags interchangeably. You can resize and do all the glorious stuff you can with regular images too. Don't be afraid of the object tag; it's just a tag, nothing big and bulky gets loaded and it doesn't slow down anything. You'll just be using the img tag by another name. A speed test shows they are used identically.
Step 2: (Optional, but awesome) Stick a default image inside that object. If the image you want actually loads in the object, the default image won't show. So for example you could show a list of user avatars, and if someone doesn't have an image on the server yet, it could show the placeholder image... no JavaScript or CSS required at all, but you get the features of what takes most people JavaScript.
Here is the code...
<object data="avatar.jpg" type="image/jpeg">
<img src="default.jpg" />
</object>
... Yes, it's that simple.
If you want to implement default images with CSS, you can make it even simpler in your HTML like this...
<object class="avatar" data="user21.jpg" type="image/jpeg"></object>
...and just add the CSS from this answer -> https://stackoverflow.com/a/32928240/3196360
Found a great solution at https://bitsofco.de/styling-broken-images/
img {
position: relative;
}
/* style this to fit your needs */
/* and remove [alt] to apply to all images*/
img[alt]:after {
display: block;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: #fff;
font-family: 'Helvetica';
font-weight: 300;
line-height: 2;
text-align: center;
content: attr(alt);
}
<img src="error">
<br>
<img src="broken" alt="A broken image">
<br>
<img src="https://images-na.ssl-images-amazon.com/images/I/218eLEn0fuL.png" alt="A bird" style="width: 120px">
If you will add alt with text alt="abc" it will show the show corrupt thumbnail, and alt message abc
<img src="pic_trulli.jpg" alt="abc"/>
If you will not add alt it will show the show corrupt thumbnail
<img src="pic_trulli.jpg"/>
If you want to hide the broken one
just add alt="" it will not show corrupt thumbnail and any alt message(without using js)
<img src="pic_trulli.jpg" alt=""/>
If you want to hide the broken one
just add alt="" & onerror="this.style.display='none'" it will not show corrupt thumbnail and any alt message(with js)
<img src="pic_trulli.jpg" alt="abc" onerror="this.style.display='none'"/>
4th one is a little dangerous(not exactly)
, if you want to add any image in onerror event, it will not display even if Image exist as style.display is like adding. So, use it when you don't require any alternative image to display.
display: 'none'; // in css
If we give it in CSS, then the item will not display(like image, iframe, div like that).
If you want to display image & you want to display totally blank space if error, then you can use, but also be careful this will not take any space. So, you need to keep it in a div may be
Link https://jsfiddle.net/02d9yshw/
I think the easiest way is to hide the broken image icon by the text-indent property.
img {
text-indent: -10000px
}
Obviously it doesn't work if you want to see the "alt" attribute.
in case you like to keep/need the image as a placeholder, you could change the opacity to 0 with an onerror and some CSS to set the image size. This way you will not see the broken link, but the page loads as normal.
<img src="<your-image-link->" onerror="this.style.opacity='0'" />
img {
width: 75px;
height: 100px;
}
I liked the answer by Nick and was playing around with this solution. Found a cleaner method. Since ::before/::after pseudos don't work on replaced elements like img and object they will only work if the object data (src) is not loaded. It keeps the HTML more clean and will only add the pseudo if the object fails to load.
object {
position: relative;
float: left;
display: block;
width: 200px;
height: 200px;
margin-right: 20px;
border: 1px solid black;
}
object::after {
position: absolute;
top: 0;
left: 0;
display: block;
width: 100%;
height: 100%;
content: '';
background: red url("http://placehold.it/200x200");
}
<object data="http://lorempixel.com/200/200/people/1" type="image/png"></object>
<object data="http://broken.img/url" type="image/png"></object>
If you need to still have the image container visible due to it being filled in later on and don't want to bother with showing and hiding it you can stick a 1x1 transparent image inside of the src:
<img id="active-image" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"/>
I used this for this exact purpose. I had an image container that was going to have an image loaded into it via Ajax. Because the image was large and took a bit to load, it required setting a background-image in CSS of a Gif loading bar.
However, because the src of the was empty, the broken image icon still appeared in browsers that use it.
Setting the transparent 1x1 Gif fixes this problem simply and effectively with no code additions through CSS or JavaScript.
Using CSS only is tough, but you could use CSS's background-image instead of <img> tags...
Something like this:
HTML
<div id="image"></div>
CSS
#image {
background-image: url(Error.src);
width: //width of image;
height: //height of image;
}
Here is a working fiddle.
Note: I added the border in the CSS on the fiddle just to demonstrate where the image would be.
The same idea as described by others works in React as follow:
<img src='YOUR-URL' onError={(e) => e.target.style.display='none' }/>
Use the object tag. Add alternative text between the tags like this:
<object data="img/failedToLoad.png" type="image/png">Alternative Text</object>
http://www.w3schools.com/tags/tag_object.asp
You can follow this path as a css solution
img {
width:200px;
height:200px;
position:relative
}
img:after {
content: "";
position: absolute;
top: 0;
left: 0;
width: inherit;
height: inherit;
background: #ebebeb url('http://via.placeholder.com/300?text=PlaceHolder') no-repeat center;
color: transparent;
}
<img src="gdfgd.jpg">
Since 2005, Mozilla browsers such as Firefox have supported the non-standard :-moz-broken CSS pseudo-class that can accomplish exactly this request:
/* for display purposes so you can see the empty cell */
td { min-width:64px; }
img:-moz-broken { display:none; }
img[src="error"]:-moz-broken { display:initial; } /* for demo purposes */
<table border="1"><tr><td>
<img src="error">
</td><td>
<img src="error" alt="error image">
</td><td>
<img src="error" alt="">
</td><td>
<img src="broken" alt="broken image">
</td><td>
<img src="broken" alt="">
</td><td>
<img src="https://i.stack.imgur.com/Mkdgc.png"
alt="A bird" style="width: 120px">
</td></tr></table>
There are several cells in this example. From left to right:
A broken image without alt attribute (baseline): show a broken image
A broken image with alt text (baseline): show the alt text
A broken image with empty alt text (baseline): show the alt text (nothing)
A broken image with alt text (our CSS): hide the broken image
A broken image with empty alt text (our CSS): show the alt text (nothing)
A functional image with alt text (our CSS): show the image
img::before also works in Firefox 64 (though once upon a time it was img::after so this is not reliable). I can't get either of those to work in Chrome 71.
The most compatible solution would be to specify alt="" and to use the Firefox-specific CSS.
Note that a broken image with an empty alt attribute doesn't guarantee the broken image icon will be suppressed, but that does seem to be the behavior in Firefox 103 and Chromium 103. Also note that this violates accessibility guidelines since screen readers will not be able to describe items with empty alt text and that may be disruptive to blind users' experiences.
Missing images will either just display nothing, or display a [ ? ] style box when their source cannot be found. Instead you may want to replace that with a "missing image" graphic that you are sure exists so there is better visual feedback that something is wrong. Or, you might want to hide it entirely. This is possible, because images that a browser can't find fire off an "error" JavaScript event we can watch for.
//Replace source
$('img').error(function(){
$(this).attr('src', 'missing.png');
});
//Or, hide them
$("img").error(function(){
$(this).hide();
});
Additionally, you may wish to trigger some kind of Ajax action to send an email to a site admin when this occurs.
The trick with img::after is a good stuff, but has at least 2 downsides:
not supported by all browsers (e.g. doesn't work on Edge https://codepen.io/dsheiko/pen/VgYErm)
you cannot simply hide the image, you cover it - so not that helpful when you what to show a default image in the case
I do not know an universal solution without JavaScript, but for Firefox only there is a nice one:
img:-moz-broken{
opacity: 0;
}
edit: doesn't actually solve the asked issue, but might still be useful.
This is what I did with SASS/SCSS. I have utility scss file that contains this mixin:
#mixin fallback() {
background-image: url('/assets/imgs/fallback.png');
background-size: cover;
background-repeat: no-repeat;
background-position-x: center;
background-position-y: center;
}
Its usage in .scss
img {
// ...
#include fallback();
}
You can use before and after as a style to prevent the broken image.
<img src="Error.src">
img:before {
content: url("image.jpg");
}
img:after {
content: "(url: " attr(src) ")";
}
In this case, if the image in the src is broken, it will use the before content, and if there is no error it will use the src.
I'm going to build on others' answers. Instead of hiding the tag (which may have important styling), feed it a dummy image:
<img src="nonexistent.png" onerror="this.src=`data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg'></svg>`;"/>
Angular way of hiding the broken image.
Inside Html file
<img *ngIf="showImage" [src]="url" (error)="showImage = false">
Inside Ts file
public showImage = true;
In theory:
Strictly "css only", we have no clean options. See other answers, I have nothing to add.
In practice:
I'd say adding a class on error event is the best way to go. Here's what I mean - and there were answers almost like this, the principle is the same, it's just more elegant if you don't add the style declarations directly. Instead, add a class that can be targeted later:
<img src="..." onerror="this.classList.add('notfound')">
And NOW you can style the hell out of it, using img.notfound as selector. You can make it a habit to add this little fragment to all your images; won't hurt anything until you style it.
Side note, before anyone comments "this is not a css-only solution": yes, thank you captain, indeed it's not. I'm trying to help with the problem itself, a problem many may have, instead of just looking at the exact wording.
This is an old question but here is something that works, the main trick here is never set a fixed height and width on the image i only use percentage.
.example {
background-color: #e7e7e7;
padding: 25px;
}
.image-box {
height: 50px;
width: 50px;
border-radius: 8px;
background-color: rgb(241, 255, 255);
color: rgb(241, 245, 249);
overflow: hidden;
display: block;
position: relative;
}
.image {
display: block;
max-width: 100%;
height: 100%;
object-fit: cover;
}
<div class="example">
<span class="image-box">
<img class="image" src="/broken.jpeg" alt>
</span>
</div>
Hide image alt with this
img {
color: transparent;
}
A basic and very simple way of doing this without any code required would be to just provide an empty alt statement. The browser will then return the image as blank. It would look just like if the image isn't there.
Example:
<img class="img_gal" alt="" src="awesome.jpg">
Try it out to see! ;)
For future googlers, in 2016 there is a browser safe pure CSS way of hiding empty images using the attribute selector:
img[src="Error.src"] {
display: none;
}
Edit: I'm back - for future googlers, in 2019 there is a way to style the actual alt text and alt text image in the Shadow Dom, but it only works in developer tools. So you can't use it. Sorry. It would be so nice.
#alttext-container {
opacity: 0;
}
#alttext-image {
opacity: 0;
}
#alttext {
opacity: 0;
}
I have an app built on Cordova and on some of my pages I am able to scroll horizontally out of my content into white space.
This is weird as I have nothing there that extends beyond my #wrapper, which is set to width: 100%.
So I was wondering if there was a way I could disable horizontal scrolling in the app altogether?
UPDATE:
Code on page as requested:
body {
background-color: #fff;
font-family:Arial, Helvetica, sans-serif;
color: #b7b8b9;
height: 100%;
width: 100%;
}
iframe{
border: none;
width: 100%;
/*margin-top: 50px;*/
}
#header{
height: 50px;
width: 100%;
}
<body>
<div id="wrapper">
<div id="header">
<div class="headerback">Home</div>
<div class="headerrefresh"><script>var pathname = window.location.pathname;</script><script>document.write('Refresh')</script></div>
<div class="headertitle"><h2>Get the Look</h2></div>
</div><!--HEADER-->
<iframe src="http://www.mbff.com.au/getthelook"></iframe>
</div>
</body>
Try to debug your page in Chrome (webkit) with the exact dimensions of your device. This solves most rendering issues for me.
I do not know the specific issue here, but it looks like one of your elements is flowing outside of the wrapper. You could for example try this in your css:
div.wrapper { overflow: hidden; width: inherit; }
Although it might be a better idea to find out why your page is expanding horizontally?
I was looking for the solution to this problem for a long time.
Finally I solved it in the following way.
I set style for bodyand html tags:
position: fixed;
width: 100%;
height: 100%;
overflow: hidden;
After that I've added div to body and set the style for it:
overflow-y: auto;
height: 100%;
So, I have got fixed body, which contains div with vertical scroll bar.
// Phone Gap disable only horizontal scrolling in Android.
// Add this code in your Phone Gap Main Activity.Initially Declare the variable
private float m_downX;
//Then add this code after loadUrl
this.appView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN: {
// save the x
m_downX = event.getX();
}
break;
case MotionEvent.ACTION_MOVE:
case MotionEvent.ACTION_CANCEL:
case MotionEvent.ACTION_UP: {
// set x so that it doesn't move
event.setLocation(m_downX, event.getY());
}
break;
}
return false;
}
});
Try adding the following code to your .html file:
document.body.addEventListener('touchmove', function(event) {
event.preventDefault();
}, false);
For the sake of completeness, I thought the answer which makes use of the official method of doing such a thing via the preference tag should be added:
<preference name="DisallowOverscroll" value="true"/>
Supported by Android and iOS according the documentation.
Default: false
Set to true if you don't want the interface to display any feedback when users scroll past the beginning or end of content. On iOS, overscroll gestures cause content to bounce back to its original position. on Android, they produce a more subtle glowing effect along the top or bottom edge of the content.
In my case it was broken styling like below
<body>
<div style="margin-left:5%; width:100%">Content</div>
</body>
which cause div to became horizontally bigger than body. I could see scroll when app run in browser. Set width to 90% (as it was initially intended) fixed the problem.
Generally, as it already pointed out here, enough to find element with wrong style which makes your page expanding horizontally and fix it.
BTW DisallowOverscroll was not helpful in above case.
