Many years ago, when I was just starting out with. NET in the 1. To me, application configuration is something that I've been adamant about since - well forever, even pre-dating. An easy to access configuration store along with an easy application access mechanism to access and maintain configuration settings through code are crucial to building applications that are adaptable. I found that the default configuration features built into. NET are pretty good, but they still take a bit of effort to maintain and manage.
So I built my own long ago, with focus on a code-first approach. The configuration library I created is small, low-impact and simple to use - you create a class and add properties, instantiate and fire away at configuration values.
The library has been updated and majorly refactored a few times over the years to adapt to changes in. NET and common usage patterns. In this post I'll describe the latest updated version of this library as I think many of you might find it useful. The very latest version of this library is now available on its own as a smaller self contained component. You can find the actual files and basic usage info here:.
But before I jump in and describe the library lets spend a few minutes reviewing what configuration options are available in the box in. NET and why I think it made sense to maintain a custom configuration solution over the years. I consider configuration information a vital component of any application and I use it extensively for allowing customization of the application both at runtime and through external configuration settings typically using.
The trick to effective configuration in any application is to make creating new configuration values and using them in your application drop dead easy. To me the easiest way to do this is by simply creating a class that holds configuration values, along with a mechanism for easily serializing that configuration data.
You shouldn't have to think about configuration - it should just work like just about any other class in your projects In my applications, I try to make as many options as possible user configurable and configure everything from user application settings, to administrative configuration details, to some top level business logic options all the way to developer options that allow me to do things like switch in and out of detailed debug modes, turn on logging or tracing and so on.
Configuration information can be varied so it should also be easy to have multiple configuration stores and switch between them easily. This is not exactly a sexy feature, but one that is quite vital to the usability and especially the configurability of an application.
If I have to think about setting or using of configuration data too much, have to remember every setting in my head ie. So what do you use for configuration? If you're like most like developers you probably rely on the AppSettings class which provides single level configuration values at the appSettings key. You know the kind that's stored in your web. All the configuration setting values are stored in string format in the appSettings section of an application's configuration file.
To access settings, the System. Configuration assembly in. NET provides a fairly easy way to access these configuration values via code from within applications:.
Easy enough, right? But it gets a little more complex if you need to grab a value that's not a string. For numeric or enum values you need to first ensure the value exists is non-null and then convert the string explicitly to whatever type, since configuration values are always strings.
Here's what this looks like:. You also have to remember the values and use the ConfigurationManager. AppSettings class. Minor but 'noisy' in application level code.
AppSettings values are also limited to a single AppSettings section inside of an application's or Web config file. Luckily you can also create custom configuration sections use the same configuration format in custom sections in a config file as long as those custom sections get declared:. The collection you get back is a read-only NameValueCollection that's easy to run through and read from.More precisely, the concept allows for an advanced 4 column layout pixels wide, on a pixel width screen, that auto-simplifies into 2 columns.
Also, it suitably fixes on the smartphone and computer tablet screen. Now you can test your website using the Responsive Design Tool. Responsive web designing is an entirely different designing version than traditional web designing, and developers especially fresher must know about the pros and cons of responsive web designing. This blog is a mighty example of the approach so we will reveal a few facts about the uses of responsive web designing.
The basic instinct might be to choose media queries to develop a responsive site. However, the hassle one faces with media queries is that new queries can pop up from moment to moment; each time, the user experiences sudden and drastic changes to the look and organization of the site.
Experts suggest using some CSS transitions to ease the jump. Pages that include data tables pose a special challenge to the responsive web designer. Data tables are extremely wide by default, and when someone zooms out to see the whole table, it becomes too small to read. When one tries to zoom in to make it readable, he or she is supposed to scroll both horizontally and vertically to look through it. Well, there are several ways to avoid this problem. Reformatting the data table as a pie or mini-graph is an approved solution.
The mini-graph fixes even in narrow screens. Images in responsive web designs are called context-aware. This particular technique serves the purpose of responsive designing in true sense as the images serve at different resolutions, ranging from larger screens to smaller ones.
The scaled images appear to change fluidly with the help of updated developer tools and coding languages, allowing designs to look sharp in every context. Responsive web designing is remarkably different from traditional designing in terms of technical and creative issues, and careful use of this can do wonders while designing.

Though nowadays this greyish grid-style static website looks a bit boring and dull, however when it was released it caused some kind of furor with its high-end layout. The main reason was that the designer primarily focused its attention on responsive behavior that was only gaining popularity those days thereby providing ordinary developers with a representative example of how regular grid-style layout should gracefully transform.
The landing page includes 3 main sections, each of which is based on image background. The flexibility solution helps to effectively form a proper structure for every standard screen size, creating a pleasant content flow for readers. With Startup App and Slides App you can build unlimited websites using the online website editor which includes ready-made designed and coded elements, templates and themes.
Stephen Caver has a topnotch website when it comes to responsiveness. You will definitely ask, what so special in it. The answer is simple, take a closer look at the front page and you will see; it consists of.
So as to say, 3 essential aspects that can be found on every website. The designer gives us a hint of how typography, grid-style markup and blog section should change according to device screen dimensions. Sparkbox demonstrates a basic structure of a corporate website. The layout is pretty simple; it is based on a standard, commonly-used set of horizontal stripes that present data in a non-intrusive manner.
Such structure is really easy to adapt to various screen sizes. The sequential arrangement of blocks deprived of embellishments undergoes changes quite smoothly and effortlessly, giving users a nice-looking and well-organized layout. Transformation from a regular left-sided blog-style magazine layout populated with numerous yummy pictures to an elementary block-by-block layout — here is how the main process of adaptation looks like in this website.In this article, I will share with you 20 best practices that will lead to clean and correct markup.
The doctype declaration should be the first thing in your HTML documents. The doctype declaration tells the browser about the XHTML standards you will be using and helps it read and render your markup correctly.
Some developers consider it a tough choice because this particular standard is less forgiving than loose or transitional doctype declarations, but it also ensures that your code abides strictly by the latest standards. The description meta attribute describes the basic purpose of your web page a summary of what the web page contains.
For each web page, you should place a consise and relevant summary inside the meta description tag. Instead, just try to be simple and straightforward in explaining the purpose of your web page. The keywords meta attribute contains a comma-separated list of key words and phrases that relate to your web page. These keywords make your web page even more meaningful. Again, just like with the description meta attribute, avoid repetition of words and phrases; just mention a few words that aptly describes and categorizes your web page.
Consider dividing your web page into major sections as the first step in constructing a website design. Doing so from the start promotes clean and well-indented code. It will also help you avoid confusion and excess use of divs, especially if you are writing complex and lengthy markup.
Your HTML is your content. Never mix both. Always create a separate CSS file for your styles.
This will help you and future developers that might work on your code make changes to the design quicker and make your content more easily digestible for user agents. Below, you can see a paragraph element that is styled using the style attribute. A simple website usually has one main CSS file and possibly a few more for things like CSS reset and browser-specific fixes. A solution to this problem is to minify take out unneeded characters such as spaces, newlines, and tabs all your code and try to unify files that can be combined into one file.

Learn about all the available HTML elements and use them correctly for a semantic and meaningful content structure. But many use it even for menial things like displaying inline elements as block elements instead of the display:block; CSS property. Closing all your tags is a W3C specification. Some browsers may still render your pages correctly under Quirks modebut not closing your tags is invalid under standards. It is an industry-standard practice to keep your markup lower-cased.
Capitalizing your markup will work and will probably not affect how your web pages are rendered, but it does affect code readability.

First, we have the Document Type Declaration, or doctype. The doctype should always be the first item at the top of any HTML file. Many years ago, the doctype declaration was an ugly and hard-to-remember mess. Now all you need is this:. Simple, and to the point. The doctype can be written in uppercase, lowercase, or mixed case. In other words, the doctype alone is not going to make your pages HTML5-compliant. In fact, you can use one of those two older doctypes with new HTML5 elements on the page and the page will render the same as it would if you used the new doctype.
In HTML5, this is no longer needed, and even the lang attribute is unnecessary for the document to validate or function correctly. The first line inside the head is the one that defines the character encoding for the document. In the past, you may have written it like this:.Building a mobile layout/pwa layout using React (hooks)
Note: to ensure that all browsers read the character encoding correctly, the entire character encoding declaration must be included somewhere within the first characters of your document. In these lines, HTML5 barely differs from previous syntaxes. The key part of this chunk of markup is the stylesheet, which is included using the customary link element. There are no required attributes for link other than href and rel.
The type attribute which was common in older versions of HTML is not necessary, nor was it ever needed to indicate the content type of the stylesheet.
When HTML5 was introduced, it included a number of new elements, such as article and section. If you had an HTML document with a recipe tag or even a ziggy tag in it, and your CSS attached some styles to that element, nearly every browser would proceed as if this were totally normal, applying your styling without complaint.
Of course, such a hypothetical document would fail to validate and may have accessibility problems, but it would render correctly in almost all browsers — the exception being old versions of Internet Explorer IE. Prior to version 9, IE prevented unrecognized elements from receiving styling.
This includes not only our imagined elements, but also any elements that had yet to be defined at the time those browser versions were developed.
That means you guessed it the new HTML5 elements. The good news is that, these days, usage of IE has dropped right off, with IE11 having fallen to around 2. As indicated by Can i useHTML5 elements are supported across all modern browsers and even even their most recent older versions. However, for those browsers you can still use this element, as long as you add approraite styling such as setting it to be a block element. Looking at the rest of our starting template, we have the usual body element along with its closing tag and the closing html tag.
