Find out moreThe font on the page is too small, and the content takes up only a small part of the screen. For convenient use, it is recommended to change the page zoom. This will improve the readability of the text and ensure more comfortable interaction with the content. Optimizing the scale will help users better perceive information and improve the overall experience of using the site.

Unlike Telegram, this platform does not have built-in settings that allow you to customize the functionality. This limitation can affect the user experience, since users cannot easily adapt the application to their needs. It is important to consider that the lack of personalization can reduce the level of convenience and user satisfaction, which is an important aspect for modern applications.

Adapting a website to different devices and screen resolutions is an important aspect of web design. This is a kind of cybertolerance that ensures comfortable interaction of users with your resource, regardless of the device, monitor or browser used (except Internet Explorer). In this article, we'll look at effective methods for adapting websites to different resolutions, which will help improve user experience and boost page rankings in search engines.
In this article, we will focus on implementing a dark theme for your website. While reading the previous article is optional, it contains more detailed explanations regarding the use of PHP scripts, which may be helpful. For a deeper understanding of the process, you can also check out the source code for this project, which is available on GitHub. This will give you a better understanding of how to adapt and integrate a dark theme on your own website.
Creating Responsive Styles
It is important to ensure that your website maintains its functionality and appearance even when the resolution changes by 1 pixel, as can happen in MS Word. To avoid display issues, it is recommended to use percentage values to specify the sizes of elements on the page. This will ensure responsiveness and flexibility of the design, allowing your site to display correctly on a variety of devices and screens with different resolutions.
When developing a website, it is important to use a wrapper that takes up the entire width of the screen. This structure ensures proper scaling of the site's content relative to the shell, which improves user experience and responsiveness. The shell helps maintain a consistent style and design, and simplifies design and layout work, ensuring a harmonious display across different devices.
The optimal amount of content, excluding the header and footer, should not stretch across the entire page. Proper structure and text length facilitate better user comprehension and positively impact SEO rankings. Content should be concise and focused to retain reader attention and increase engagement. Focus on the quality of information, not its quantity.

The width of the text block is 80% of the page width. Without this limitation, reading small font on large screens could be a real pain in the neck. Such limits are important for ensuring ease of text perception and improving user experience. The correct block width promotes ease of reading, reducing eye strain and allowing you to focus on the content.

You can set the maximum width in pixels. This will allow you to control the display of content on the pages of your site, ensuring better readability and visual perception of information. Setting the maximum width helps adapt the design to different devices, improving user experience and SEO optimization.
Reading the text will be comfortable and convenient regardless of the monitor size. Optimizing content for different screen sizes ensures easy access to information, which is especially important for users reading on mobile devices or large displays. Correct adaptation of text improves user experience and promotes better perception of the material.

Creating styles for individual resolutions
As in the case of the dark theme, you can create several style files, each of which will be optimized for different screen sizes. Let's start with a stylesheet for medium-sized monitors—normal.css. This file will contain settings that will ensure page elements display smoothly on devices with a normal screen width, improving user experience and website responsiveness.
In addition to the main stylesheet, two additional files will be created: small.css and big.css. These files are included in the HTML document using a separate link element, allowing for efficient management of styles for different screens and devices. This approach ensures the responsiveness of the web page, improving user experience and optimizing content loading.
Now we need to implement the ability to select a zoom level for the user. To do this, we'll add buttons that will allow users to select the appropriate zoom level.
Include a script that will switch between stylesheets. This will allow users to choose between different themes for your website. Make sure the script correctly loads and applies styles to improve user experience and enhance the appeal of your content. Proper implementation of this feature will not only improve the visual appeal of your site, but can also help increase the time users spend on the page.
The script not only changes the page style, but also remembers the user's choice in the browser. This allows the selected style file to be automatically included the next time the page is opened. The following PHP code is used to implement this function:

Note that the text block has increased in width for small screens. It's not the case that white space improves the appearance of a page. Optimizing content for mobile devices is important because it improves user experience. Ensure that text information is accessible and easily readable on all devices to improve navigation and user satisfaction.
Automatic Scaling
JavaScript can detect the user's browser window size, allowing you to include the most appropriate stylesheet for the current screen size. This improves user experience and the responsiveness of your web page. An example of code for implementing this function might look like this:
The page will automatically scale.
