Responsive photo web code

When design moves online for content experiences, it demands mixing art with the science of dev and coding. Text over an image looks really nice in a magazine, and it can look nice on the web too. Such design can be challenging to implement responsively so the experience works across platforms of different sizes. In particular, note how it responds to different screen widths. So what does it take to do that?

Responsive Images in WordPress

Responsive web design is something you hear a lot about these days. The moment I really started to get into responsive design was a few months ago when I started to realise that 'responsive' is not just about scaling your websites to the size of your visitors screen but much more than that. Truly responsive web design is about completely adjusting your website to the visitor's device. It does not just include scaling, but just as important is reducing the data you transfer to visitors who are on a slower connection like 3G or even EDGE.

One of the most data consuming elements on a website are the images. To reduce the data they give to our website we can replace them with more suitable images for the device our visitor is using.

The element is not supported in any browsers yet and until it is we'll need either a back-end or a javascript solution to get this done. There are a number of plugins for this already out there.

However, when I searched for one I didn't really find one that suited my needs. Most of them required some kind of additional javascript to be imported next to the plugin and the HTML markup they use seemed a bit dirty and unorganized to me.

I got the idea that there might be a cleaner solution possible. This is when I came up with the idea for responsive-images. Which is a simple and lightweight javascript plugin 1kb for responsive image replacement. It uses a clean HTML markup and does not require any additional javascript in order to work. Using the data-src2x attribute it is possible to specify the images the script should use in case the device has a retina display. Something that bothered me about this markup though, is that all of the image paths are defined twice.

So to make the markup a bit cleaner there is also the option to only change the data-src-base path for retina devices using the data-src-base2x attribute. Browsers are too quick for us! In order to provide the fastest loading time possible, browsers preload all of the images that they can identify -- Choosing A Responsive Image Solution, Smashing Magazine. The problem is though, as described by Smashing Magazine, that when you set a src attribute the browser will preload the image before any javascript or even CSS is applied.

This would make double loading of images unavoidable. I don't see any workaround here yet thoughts, anyone? The good part is that the plugin even works in browsers like IE5 and Opera Mobile and that there are no known unsupported browsers yet, which makes it pretty safe to leave out the src attribute. How the plugin itself works is pretty easy. It loops through all the images on the page and first checks if the image contains a data-src attribute to determine if the image is supposed to be responsive.

Now we determine if we are talking about above or below by simply calling an indexOf. Now, before matching the against our visitors viewport we first have to determine if their is any lower breakpoint available. In this case there is a lower breakpoint set of Like above, we split the string at its square bracket and colon. Now we check if the viewport is between our two values. If this is the case then we simply change the image source to the source that belongs to the breakpoint.

As soon as the plugin was functional I started doing some browser tests. I tested on iOS, android and various desktop browsers. Since I really wanted to see was how far I could raise the bar also older browsers were tested including IE5, Opera On the phones I tested devices including Android 1. While doing these tests I ran into a few problems. Two were for IE but one was for our beloved iOS Easy right? Just put document. That's what I thought. But it appears to be a bit more complicated than that.

I haven't been able to find a javascript only solution for this yet and am not sure if there is one. I would however like to investigate this some more. If you have thoughts about this, let me know! To determine if an image has a data-src attribute the scripts makes use of the hasAttribute method. The problem with this however is that IE7 and below do not support this.

For them I had to create a workaround. Those are the basics of this all. However, after this I bumped into another problem. I thought: IE7 and below do not support hasAttribute so why not just define the hasAttribute method myself in case it does not exist? A prototype function is out of the question since IE7 and below do not support them either so I created a normal one. Do you already see my mistake here?

Declared functions are loaded before any of the other code is executed which makes our if statement invalid and results in a Object does not support property or method hasAttribute error.

Let's try that again. Now if we use function expressions, the code will only load when the interpreter reaches that line. Which makes our if statement work. Next up is the addEventListener method which is not available available in IE8 and below. They instead use the attachEvent method. Just like for the hasAttribute method I also used a simple workaround here by first checking if the addEventListener method exists.

I've even caught myself reading the post For those of you that We all know that we can set a link's :hover color, but what if we want to add a bit more dynamism and flair? You require jQuery in order to use your in order for people to use your plugin which increases the payload for smaller websites who do not require any other jQuery functionality.

This can get a bit messy since the attribute names are quite long. Defining a 2x image is done by adding the filename in the same attribute which is nice but requires you to also redefine the path. Like when I would like to define a pixels wide breakpoint. I would have to use something like:. This looks like a really good solution. From what I read elsewhere yesterday it appears W3C may be moving away from the idea of and its associated syntax and towards an type of syntax and tag.

Hey, yeah, hope the solution W3C comes up with will we widely supported quickly after the release so the whole responsive images thing can be done natively. Strange effect in Chrome on Nexus 5 — 1st view of demo in portrait, I get.. Hey David, Thanks for noticing that! I will make it an issue on the Github page and look into it as soon as possible. A nice improvement would be speed.

Maybe detect download of the first image download and then if speed is ok, update to retina. Hey vic! The internet speed of the user if very important! I am currently still looking into this to see if it would be possible to check what type of connection our visitor is using and determine what image to use from there. Updates on this can be found on the Github page Github page. I guess the only appropriate javascript solution these days is to load a dummy file via Ajax and measure the time it takes to load.

Hi MaxArt! Haha had that before the getAttribute actually but it kept returning undefined in IE6. I will look into it further though, thanks for bringing it up! Because they register handlers on dom ready. Wondow onload. Hey Vincent, yeah could be a good idea to change the on window load to something a bit earlier.

Using a transparent image would not help with the SEO and if the javascript not works on a page still show nothing, but I might be off here? Is it just me, or are you missing commas in your first 2 responsive-images. In the first line of data-src and data-src2x attributes.

This is neat.

How to create a responsive image with CSS?

Webflow creates variants of your uploaded images to make sure they're responsive, look great, and load quickly on any device. This can help your mobile pages load up to 10 times faster. To do this, Webflow creates a set of variants for each image upon upload details below , then encodes instructions for your browser to know when to serve each variant. We measure your images and generate responsive variants as you work on the current page. But you may make changes that affect images on other pages say, by updating a symbol or class. If you created your site before September 14th, , you'll need to walk through a quick process to generate responsive images on your site. Next time you open the Designer, you'll see a modal asking you to start this process.

Keep in mind that your images will not only need to fit each large screen, but will also need to work effectively on each smaller screen. The first step to solving this problem is image optimization. The next step, however, begins with understanding how browsers interact with those images. Optimizing images for responsive design requires that those images quickly scale to fit desktop, tablet, and phone screen sizes. There are a couple of solutions that have been commonly implemented by the industry and, while neither is perfect, they do allow web developers to effectively follow responsive design principles. The most popular method for preparing images for a responsive website is to scale those images in code. You can see an example of this code below:.

A Guide to Responsive Images on the Web

While developing the new website for CodeCaptain, we were looking at ways to prevent article pages from reflowing jumping when our responsive images loaded. The first and most obvious way to prevent reflow is to pass in the width and height of the image as attributes. Using a nifty padding-bottom trick, we were able to reserve space on the page by looking at the aspect ratio of the responsive images, let me give you an example. By knowing this aspect ratio, you can calculate the height of an image, by only knowing about the width.

Flexible Images and Media

Not to mention, you also have to consider tablets, 2-in-1 laptops, and different smartphone models with different screen dimensions when coming up with a design. With responsive web design , you can make sure your website looks its best on cell phones, tablets, laptops, and desktop screens. This guide will give you everything you need to know about responsive website design, including definitions, a step-by-step walkthrough, examples, and more. Responsive design is an approach to web design that makes your web content adapt to the different screen and window sizes of a variety of devices. For example, your content might be separated into different columns on desktop screens, because they are wide enough to accommodate that design.

How TO - Responsive Images

The picture element is a markup pattern that allows developers to declare multiple sources for an image. By using media queries, it gives developers control as to when and if those images are presented to the user. The picture element is one part of the HTML specification. The srcset and sizes attributes extend the img and source elements to provide a list of available image sources and their sizes.

Jakob Jenkov Last update: Responsive images means images that can be scaled to fit the content blocks they are displayed in. One core concept of responsive web design is that content blocks can be resized to fit the width of the browser window. While some HTML is naturally scalable, images typically have a fixed width and height and thus represents a challenge to a scalable layout. In this text I explain how to overcome that challenge.

You also need to make sure that you are serving the right images to your users depending on their device capabilities. It means not relying on browser resizing to display images on screens with varying widths or sending a high-resolution image to small devices with a low resolution display which could result in a huge waste of users' data. Although the physical pixels of the device is x , if the browser tried to use every single pixel to display content on a 5. Which brings me to the concept of logical pixels a. The DPR is defined by the device manufacturer. Simply put, it refers to the number of physical pixels contained in one logical pixel. For example, a device with a DPR of 2 means that one logical pixel contains 4 2 x 2 physical pixels.

Choosing A Responsive Image Solution

Finally, true responsive images are becoming a reality on the web — in pure HTML, without convoluted hacks. Before you start using responsive images in your design, you always have to answer the following four questions:. When creating these examples, I had this night shot of the Oslo Opera house in my head — it might be useful for your reference. Before you start looking at the different examples though, here are a couple of things to keep in mind:.
