Adaptive yandex map

Smartphones on the Android operating system won universal recognition. Mobile devices enjoy like children school age So the elderly retired. The main advantage of the smartphone, in front of the usual telephone, is its wide opportunities. First, the device has an operating system, which allows you to install additional software, replacing uncomfortable pre-installed programs or even missing possibilities. For example, using third-party applications, you can significantly improve the quality of the photo and video.

Adaptive YandexMaps in a modal window in bootstrap?


My name is Vladimir, and I develop mobile front-end for Yandex Mail. Our apps have had a dark theme for a while, but it was incomplete: only the interface and plain emails were dark. Today I'll tell you how we fixed this problem.

You will learn about two simple techniques that didn't work for us and the method that finally did the trick — adaptive page recoloring. I'll also share some ideas about adapting images to a dark theme. To be fair, darkening pages with custom CSS is a rather peculiar task, but I believe some of you may find our experience helpful. Before settling on our magic color-bending technique, we tried out two really basic options: applying either additional dark styling or a CSS filter to elements.

Neither option worked for us, but they might be more suitable in other cases simple is cool, right? This is a dead-simple option, which logically extends the app's own dark CSS theme. You just put extra dark styles onto an email container or, in general, onto a container for the user-generated content to darken :.

However, any styles on the elements inside the email will override our root style. And no,! The idea can be taken a step further by preventing inheritance:. In this case, you can't do without! This also happens to override most inline styles the ones with inline! Our style eagerly paints everything the same color, thus introducing another problem. There's a chance the designer wanted to say something with the way they arranged the colors you know, priorities, pairings, all that designer stuff , and we just took their idea and threw it out the window.

Not a nice thing to do. If you don't respect designers as much as I do and decide to go with this method, don't forget to handle the not-so-obvious things:. From a technical point of view, this is a solid method: it takes three lines of code OK, thirty for a production-ready version with all the edge cases taken care of , it's compatible with all the browsers in the world, it works on dynamic pages out-of-the-box, and the way CSS is attached to the document is completely irrelevant.

There's also a nice bonus: you can easily tweak the colors in the style to match the main colors of the application for example, make the background bbbbb8 instead of black. By the way, this is how we used to darken emails before.

OK, let's assume we can find all these elements, explicitly mark them, and change their colors back, too. The good thing about this method is that it preserves the original brightness and contrast balance. On the other hand, it's full of problems that outweigh the advantages:. This method would work for emails with neutral-colored text, but I've never met anyone with an inbox full of such content.

On the other hand, filters are the only way to darken elements without accessing their contents — frames, web components, or images. And now it's time for magic! Based on the drawbacks of the first two approaches, we made a checklist of what we should take care of:. So, you need to change the colors of the styles to make the background dark. Why not just do that, literally? Take all the styles, extract the color-related rules color , background , border , box-shadow , and their subproperties , and replace them with their "darkened" versions: darken the background and the borders but not as much as the background , lighten the text, etc.

This method has an incredible advantage that will warm any developer's heart. You can configure color conversion rules for each property — yes, using code! With a bit of imagination, you can fit the colors to any external theme, perform any color correction you wish for example, do a light theme instead of a dark one, or a theme of any color you like , and even add a little bit of contextuality — for example, treat wide and narrow borders differently.

The disadvantages are what you'd expect from an "everything-in-js" approach. We run scripts, mess up style encapsulation, and parse CSS with regex. The wrapper code — normalization, locating styles, parsing — is quite trivial. Let's see how exactly our magic converter works. Darkening a color isn't as simple as it sounds, especially if you want to preserve the hue for example, turn blue into dark blue, not orange. You can do this in ordinary RGB, but it's problematic.

If you're into algorithmic design, you know that in RGB, even gradients are broken. Meanwhile, working with colors in HSL is a real treat: instead of Red, Green and Blue, which you have no idea what to do with, you have the following three channels:.

You can think of it as a cylinder. We need to turn this cylinder upside down. Sometimes we get lucky and the custom design of the email or a part of it is already dark. This means we don't need to change anything — the designer probably did a better job at picking the colors than our algorithm could ever dream of.

If its value is higher or lower for the text and the background, respectively than the threshold which you can set , just leave it alone. Even though we did not need any of this many thanks, sanitizer, you saved my day here , I'll list the extra features an adaptive theme needs to darken entire pages and not just goofy static emails from the '90s.

Fair warning: this task is not for everyone. Changing inline styles is the simplest case that messes up our dark pages. It is common, but there's a simple fix: add MutationObserver and fix inline styles as soon as the changes occur.

And CORS doesn't make things better. Here you'll also need to use MutationObserver , but every change will incur more processing. Things get really wild when CSS variables come into play. You can't darken the variables: even if you guess that a variable contains a color based on its format although I would advise against this , you still don't know what its role is — background, text, border, or all at once?

Moreover, the values of CSS variables are inherited, so you need to track not only the styles, but the elements they are applied to, and this quickly escalates out of control. In our case, when the sanitizer leaves only inline styles, adaptive darkening at the CSS level works like a charm: it gives higher-quality darkening, doesn't disrupt the original structure, and is relatively simple and quick. Extending it to tackle dynamic pages is probably not worth the trouble, though.

Fortunately, if you're working with user-generated content and you're not developing a browser, your sanitizer likely works the same way. Image darkening is a separate issue that bothers me personally. It's challenging, and gives me an excuse to finally use the phrase "spectral analysis".

There are several typical problems with images in a dark theme. Some images are just too bright. These give us the same trouble as the bright emails we started our quest with. Since writing newsletter CSS isn't much fun, some guys like to skip corners by inserting complex layout as an image, which prevents darkening. When I see that, my inner perfectionist groans in frustration.

These images should be dimmed, but not inverted, unless you want to scare your users. Then there are dark images with real transparency. This is a typical problem with logos — they are designed with a light background in mind, and when we replace it with a dark background, the logo disappears into it.

These images need to be inverted. Somewhere in between are images that use a white background that's supposed to represent transparency. In the dark theme, they simply end up in a weird white triangle.

In a perfect world, we could change the white background to a transparent one, but if you've ever used a magic wand tool, you know how hard it is to do that automatically. Interestingly enough, some images carry no meaning whatsoever. These are usually tracking pixels or "format holders" in particularly bizzare layouts.

You can safely make them invisible say, with opacity: 0. To figure out how to adjust an image for dark theme, we need to look inside and analyze its contents, preferably with a quick and simple method. Here's the first version of an algorithm that solves this.

First count the image's dark, light, and transparent pixels. As an obvious optimization, just a small subset of pixels can be considered.

Next, determine the overall brightness of the image light, dark, or medium and whether there's any transparency. Invert dark images with transparency, dim opaque bright images, and leave the rest unchanged. I was really happy about this discovery until I came across a charity newsletter featuring a photo of a lesson at an African school.

The designer centered it by adding transparent pixels on the sides. We didn't want to get involved in a story about offensive image recognition, so we decided to leave image manipulation out of our first iteration. In the future, we can prevent such problems by employing that heuristic I call "spectral analysis". That is, counting the number of different hues in the image and only inverting if there are aren't too many of them.

You can use the same method to recognize bright sketchy images and invert them, too. To design a full-fledged dark theme, we had to find a way to darken emails that contain custom formatting — and we did. Neither of them hit the mark: the first one was too hard on the original design, and the other simply didn't work well.

In the end, we decided to use adaptive darkening. We take the styles apart, replace the colors, and put them back together. We're currently working on applying the dark theme to images. To do that, we need to analyze their contents and then only adjust some of them.

If you ever need to change the color of custom HTML snipets to fit it into a dark theme, keep three methods in mind:. Simple methods Before settling on our magic color-bending technique, we tried out two really basic options: applying either additional dark styling or a CSS filter to elements. Overriding styles This is a dead-simple option, which logically extends the app's own dark CSS theme. If you don't respect designers as much as I do and decide to go with this method, don't forget to handle the not-so-obvious things: box-shadow.

For example, in this image map can be clicked both in the circle as the square:. How can you do so that the areas on the map are adapted as the image? Complementing the answer of Philippe, could you make use of any plugin as jQuery RWD Image Maps , which allows you to recalculate the coordinates of the area of the map and be able to adapt to the size of the window. The Snippet is taken from here. You could simulate the image map with links and css, not sure if it is what you need. The alternative is SVG, for example, in which you can even put the onclick on each one of the elements.

all-audio.pro As I understand it, after opening a modal window need to "redraw" the map to make it fit.

A website is a place where you can publish detailed information about the company, services, terms of order, and performance of services, contacts, and details especially hotels. The site informs your customers all year round, night and day. And even if you have a well-designed website, the question arises: how to attract visitors to your website? The site structure is the foundation. The more convenient it is the better each block is worked out, and the more likely it is that the user will stay on the site and book a room. By contrast, if we talk about a luxury hotel, but the site is a complete mess, the potential customer may not even get to the description of the rooms and the booking form. Use your imagination and love your guests — they will definitely appreciate it and come back again!

The standard controls in the all-audio.pro API are adaptive, meaning they automatically adapt to the size of the map and the size of the screen.
