Web development has become one of the most important parts of many different sectors today. This intense interest in the use of the internet comes from the concept of web development. The tools and methods used in web development processes are very important.
What Are HTML, CSS, JS and What Do They Do?
What is HTML?
HTML stands for Hypertext Markup Language. It is a standard markup language used to build the foundation of web pages. Web browsers, which have been in use since its inception up to now, display and interpret websites using HTML codes.
HTML is a set of tags used to determine the hierarchy in which all materials such as text, images, videos, etc. that should be included in the website are displayed within the website. The tags used are read by browsers and displayed to users.
Does Learning HTML Alone Make You a Webmaster?
The answer to this question is definitely no. If we concretize websites a little more and compare them to a building, a website made using only HTML is like a building with only columns and floors. It is unfinished, unusable, and unaesthetic.
What Are the Basic Fundamentals of HTML Pages?
- <head></head> tags, which define the beginning and end of the document, tell us that this tag is closed and ends when the (/) sign is usually added to the same tag.
- Head tag, as the name suggests, can be called the title of the website. Important information about the site and page settings are defined in tags.
- Here are a few examples:
- The title text of the page,
- How it will appear in google searches,
- The files to use.
- Here are a few examples:
- The body tag is the body of the website. All content that users see is included in the Body tags. The Body tag must come after the Head tag on the page. Its usage is as <body></body>.
- If a page has a title, it should also have a footer. Here, the Footer tag comes into play. Its use is not mandatory, but it is recommended to help users better understand the page. The <footer></footer> tag is a tag introduced with HTML5.
The skeleton structure of a simple website is as follows:
<!DOCTYPE html> <html> <head> <!-- The head section contains page information and style definitions --> </head> <body> <header> <!-- content at the top of the page --> </header> <main> <!-- main content of the page --> </main> <footer> <!-- content at the bottom of the page --> </footer> </body> </html>
What Is CSS? What Does It Do?
CSS, in other words Cascading Style Sheets, is a style language used to control the display and layout of web pages. We get help from CSS codes to make the HTML structure used in the example we mentioned above a little more user-oriented. Otherwise, only plain text will be projected onto the screen.
CSS has a great impact on how the visuals, fonts and hierarchy of the web page will be. It is one of the first stages of front-end development. It allows us to make pages that can interact with users at least a little.
The images of a web form where the use of CSS is reduced by half will take place in the form of before and after. Even if the use of CSS is not completely removed, a pretty big difference can simply be observed on form elements.
Some of the popular CSS frameworks are;
What is a Framework?
Frameworks are code snippets created to facilitate the work of software developers and speed up the software development process. It offers ready-made solutions to the developer. Frameworks are used not only in web development but also in areas such as mobile application development, desktop application development and game development.
Some of the popular web development frameworks are as follows;
What are front-end frameworks?
Front-end frameworks are pre-made code snippets that front-end developers use. To give a concrete example, the lines of code we need to write to style a button will be approximately as follows:
border: 1px solid transparent;
padding: 0.375rem 0.75rem;
transition: color .15s ease-in-out,background-color .15s ease-in-out,border-color .15s ease-in-out,box-shadow .15s ease-in-out;
Instead of writing so much CSS code, if we call the bootstrap library between the head tags of our website, we only need to give the btn class to the button object.
We can call the bootstrap library by adding the following code into the <head> </head> tags of our website:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
Front-end frameworks are needed because they provide these practical solutions. For example, CSS Flex and CSS Border can perform related styles in one go by calling the relevant class on the framework instead of giving styles that will repeat continuously.
Some popular (CSS) front-end frameworks are;
- Semantic IoT
What Is the back-end? What Are Back-end Frameworks?
Back-end is a form of coding that allows the system that the user sees to run on the back end. Unlike Front-end coding, Back-end codes are executed by the server, not the browser. Back-end examples in a web application can be as follows;
- User login system,
- Session management,
- API integration,
- Security operations,
- Database operations,
- E-commerce systems,
- File upload,
- Sending an email,
- Real time application development.
Back-end frameworks are ready-to-use code snippets that are pre-built to make the developer’s job easier, just like other framework applications. It gives the developer a coding style that is different from others within certain rules.
