i am working on a Django project, where we built a Bootstrap carousel of images.
My task now is to try and lazy load those images.
How would I write a view in Django and in HTML that would request the next image in the list and the render it.
The carousel does have a back and next button that could be used as an event but I am unsure how I would go about partially rendering the slideshow.
Thanks in advance.

I added a gif image in my html page but it was in the last section when I load my page it work immediately I want a way to pause or stop it until the user scroll down and reach it to work
Assuming you're using an animated gif, I think something called 'lazy loading' may help you. Essentially, this doesn't load an image until it's in view.
Typically lazy load is used to make pages finish loading faster. But in your case it could prevent your animation playing before it's in view.
Lazy loading images is done with javascript and you could use for example this jQuery plugin: http://luis-almeida.github.io/unveil/
I hope this helps you.
I'm building wallpaper/gallery ionic app.I am trying to design app in such a way that users can click on the image shown as ionic card and and users will be shown the image in full screen probably using ionic slides with a button for downloading image below.
I know for a fact that using same code for displaying images full screen more than one time is not a good practice.
Is there any way i can use the same ionic slide code multiple times showing corresponding image full screen.
FYI,here is the code,
<ion-slidesj zoom="true">
<ion-slide>
<div class="swiper-zoom-container">
<img src="assets/img/dog.jpg">
</div>
<ion-label>Woof</ion-label>
</ion-slide>
<ion-slide>
I want to use above same code multiple times with different img srcs for corresponding image user clicks.
Thanks.
You just need to create Angular/Ionic custom component here.
ionic generate component MyImageSlider
After that wrap your image slider inside it and send your image URLs dynamically to that custom component when a user clicked the ionic card.
You can see how to create a custom Component here.
You can use a loop to iterate through all your. Store all images path in a array of string and then iterate through that array. And pack your block of code in this loop .
I am surprised by the display system of Youtube. When we are on the main page https://www.youtube.com/ and we click on one link of the menu at the left side to go to this page for example https://www.youtube.com/feed/trending, there is no flashing when going from one page to another.
It looks like the new page is preloaded and then display only the difference with the page before.
Furthermore there is the progress bar system (like this one http://ricostacruz.com/nprogress/) which ends all the time at 60% on the current page, then starts at 60% on the new page and go straight to 100%.
Any clue how they do that? Javascript, specific server configuration?
Thanks
This is a feature of frameworks like Angular or React, as a single page app (SPA), which use data APIs to load data and two-way binding to dynamically update only the things that have changed.
I was wondering if there were any online resources to creating a fullscreen modal without using Bootstrap. I'd like to learn how to implement this myself. The full effect would be a scrollable overlay for a projects section so if the user wants to view more of a project they can click on the image and a fullscreen box overlays the current page with the ability to close when done.
I think, this animatedModal will handle it.

Im using Bootstrap on a website where a page has a few modals.
Using Chrome Dev Tools i was testing the network usage and noticed that the images in the modal view are called/pre-loaded when the page loads - I guess that makes sense they are all in divs on a single page.
So my question is it possible to avoid that div from running only until the actual link to a particular modal is clicked?
Thanks.
Use $.get or $.load in the click event handler of the button to display the modal.
Note that the HTML data you load via this ajax technique must be in the right bootstrap modal template.
