What is CSS?
As it is known, HTML text formatting gives many options on behalf of many different points of the site. The CSS program, on the other hand, offers this option at a higher level with a wide range of opportunities. This system, which is known as Cascading Style Sheets with its long name and named Style Template in Turkish meaning, allows you to prepare universal templates for each page in the site within a wider world of options.
In other words, for example, if any letter is to be taken into consideration; It gives the opportunity to change many different features such as size, font or color in detail. As CSS, the most striking point of this system is its uniquely flexible usage opportunity. Generally speaking, there is no need to change too many fonts or colors on behalf of all pages in a website. At this point, the main task of CSS here is to do all these operations on web pages at once instead of processing them one by one on each page. One of the biggest privileges of this is that all these changes to be made on dozens of site pages during the update are not dealt with separately.
What are the CSS Versions and Features?
The technical features of CSS are determined by the W3C organization, which stands for World Wide Web Consortium. There is a group named "CSS Working Group" in W3C and various studies on the technical features of CSS are carried out by this group. The work done by the CSS Working Group is discussed by the W3C members and relevant innovations are implemented after they are formally approved.
Each new CSS version builds on the previous version and is named with version numbers such as CSS 1, CSS 2, CSS 3. The first CSS version was CSS 1 published by W3C on December 17, 1996. CSS 1; is a version that contains basic controls for web page elements such as fonts, text, backgrounds, tables, and borders.
CSS 2, which is a higher version of CSS 1, was published in 1998 and has various innovations to design more functional websites. It has various advanced features such as advanced positioning options, Z-index, audio style sheet support, bidirectional text and shading. With the version of CSS 2.1, the errors in CSS 2 have been eliminated and a more stable operation has been provided.
CSS 3, published by W3C in June 1998, is the latest version of CSS. CSS 3 built on previous versions; It has brought new features such as selectors, colors, namespaces and media queries. With many CSS 3 features such as rounded corners, transitions, shadows, animations, and gradients, you can design advanced web pages that bring more visual and user experience to the fore.
CSS and Coding
There are some situations that need to be done while coding CSS. At first, CSS codes are placed inside HTML codes, that is, they are written. The type of body or head sections can be chosen according to the type. With these operations, external CSS files, which can also be said as a backup, can be prepared and removed from the HTML when it is necessary to take action. As it is known, as in all different programming, Netscape and Internet Explorer look at this process from different angles. For this reason, it is an advantageous situation to write a coding that both sides can look at with the same perspective.
What Are CSS Usage Styles?
CSS software has a very flexible and useful structure that allows the properties of web pages to be controlled individually or collectively. In CSS; You can add your codes to your web pages in 3 different ways: external style sheet, internal style sheet and styles written inside the tag. Each method has various advantages according to its intended use and place.
If you want to control the style properties of multiple web pages with just one CSS page, you can add CSS code with the external style sheet method. You can use the internal styling method to control the elements on a single web page and make the necessary formatting. The codes written in the tag only check the relevant tag and are not recommended to be used unless necessary.
What can be done with CSS?
As a general definition, quite a lot of options that cannot be done via HTML can be done within this system. Among these, you can define the background image, color or size of a certain element or the position of the page in any page content of a site, and many other different properties with the help of CSS. Thanks to the CSS file, the style of each page can be adjusted, so the size of the pages is reduced and the load that is more than necessary is quite light. Moreover, the CSS format has a language structure that does not pose much of a challenge to understand and learn. If CSS will be used at this point, then you must have basic knowledge of HTML. CSS code writing is used in English as in most coding systems. At this point, it will be sufficient to know the English words to be added in the code software.
Many operations such as font sizing, different heading styles, border ornaments, shading, horizontal and vertical menus, page layout and color operations can be performed using only CSS codes. CSS codes also allow for various actions on web pages, such as basic transition effects and simple animations. You can make your sites more interactive with the codes you write on the table and form elements.
CSS Snippets and Page Content Placement
CCS consists of three different parts in terms of rules. These sections include definition and selector sections. The definition consists of a value and a feature at this point. In other words, the selector (Value) is its ID or name on behalf of html. At the feature point, some values are used as standard. Among them, of course, these properties are about 120 and they have their own values as properties. After the CSS codes are written, it remains to add them to any page. It is possible to affect all HTML elements after insertion. When the CSS code system is completed, all page contents on the website can be changed easily.
What Are CSS Libraries and Their Advantages?
CSS libraries, called CSS Framework, are highly advanced tools that make CSS coding operations easier and more functional. Using CSS libraries has many benefits for web developers, such as saving time, writing team code and reducing mistakes.
