Frontend - UI development Guide
HTML, HyperText Markup Language, gives content structure and meaning by deﬁning that content as, for
example, headings, paragraphs, or images. The three common HTML terms you should begin with are
elements, tags, and attributes. HTML is like constructed building without painting colors and interior.
Elements:
Elements are designators that deﬁne the structure and content of objects within a page. Some of the
more frequently used elements include multiple levels of headings and paragraphs. Ex - <a>
Tags:
The use of less-than and greater-than angle brackets surrounding an element creates what is known as a
tag. Tags most commonly occur in pairs of opening and closing tags. Ex - <a> … </a>
HTML

Attributes:
Attributes are properties used to provide additional information about an element. The most common
attributes include the id attribute, which identifies an element; the class attribute, which classifies an
element; the src attribute, which specifies a source for embeddable content; and the href attribute, which
provides a hyperlink reference to a linked resource. Ex - <a href="http://google.com/">Google</a>
Not all elements consist of opening and closing tags. Ex - <img>, <br/>
HTML

Semantic Elements:
Semantic elements = elements with a meaning. A semantic element clearly describes its meaning to both
the browser and the developer. Examples of non-semantic elements: <div> and <span> - Tells nothing
about its content. Examples of semantic elements: <form>, <table>, and <article> - Clearly deﬁnes its
content. In HTML there are some semantic elements that can be used to deﬁne different parts of a web
page.
HTML Accessibility:
Accessibility is strongly related to universal design which is the process of creating products that are
usable by people with the widest possible range of abilities, operating within the widest possible range of
situations.
HTML

W3C Standards:
The World Wide Web Consortium (W3C) develops international Web standards: HTML , CSS , and many
more. W3C's Web standards are called W3C Recommendations.

HTML

CSS:
CSS stands for Cascading Style Sheets. CSS is the language for describing the presentation of web
pages, including colors, layout, and fonts. It allows one to adapt the presentation to different types of
devices, such as large screens, small screens etc. CSS is independent of HTML and can be used with any
XML-based markup language.
CSS Selector:
CSS selectors are used to select the content you want to style. Selectors are the part of CSS rule set. CSS
selectors select HTML elements according to its id, class, type, attribute etc.
CSS Selectors - Element, Id, Class, Universal and Group Selector | Pseudo | Combinators

CSS Media Queries:
The media queries are a special syntax for CSS that allows us to define some styles that will only be
applied in the case that defined conditions are met.
Media queries are useful when you want to modify your site or app depending on a device's general type
(such as print vs. screen) or specific characteristics and parameters (such as screen resolution or
browser viewport width).
Media queries add no specificity to the selectors they contain, but source order still matters.
CSS / CSS3

CSS Units:
CSS has several different units for expressing a length, Height and Sizes.
Ex - px, rem - relative to font-size of the root element, em - relative to the font-size of the element, vw -
relative to 1% of the width of the viewport, vh - relative to 1% of the height of the viewport, % etc.
CSS Naming conventions:
One of the diﬃcult things in computer science and programming in general is naming things and naming
things in CSS is no different. Naming conventions in CSS are hugely useful in making your code more
strict, more transparent, and more informative. Ex - BEM, SMACSS, ITCSS, OOCSS, AMCSS
DRY CSS Rule - Don't Repeat Your CSS
CSS / CSS3

CSS3:
CSS3 is the latest evolution of the Cascading Style Sheets language and aims at extending CSS2. It
brings a lot of long-awaited novelties, like rounded corners, shadows, gradients, transitions or animations,
as well as new layouts like multi-columns, ﬂexible box or grid layouts.
SCSS (Syntactically Awesome Style Sheets) / LESS (CSS Preprocessor):
SCSS/LESS is a preprocessor which lets you use features that aren’t a part of the wider CSS standard yet,
and provides better workﬂows for maintaining your stylesheets. With SCSS/LESS preprocessor, you can
reduce the amount of times you repeat yourself and ensure you’re writing clean, maintainable code for
the future. Dry (don't repeat yourself) code is much better then wet code (write every time).

JavaScript:
JavaScript is a Front-End side scripting language that enables you to create dynamically updating
content, control multimedia, animate images, and pretty much everything else in HTML. HTML and CSS
are languages that give structure and style to web pages, JavaScript gives web pages interactive
elements that engage a user.

JavaScript frameworks and libraries - Angular, React and Vue etc:
javaScript frameworks are collections of JavaScript code libraries that provide developers with
pre-written JS code to use for routine programming features and tasks—literally a framework to build
websites or web applications around. JavaScript framework is an application framework written in
JavaScript where the programmers can manipulate the functions and use them for their convenience.
JavaScript was initially used only for the client-side. However, these days, JavaScript is used as a
server-side programming language as well.

Advance Frontend Technologies

The ability to better solve problems and write neat & elegant code
is an important criterion to set us apart from other common
developers. Meanwhile, to keep up with the high-speed
development of tech and grasp our opportunities, we need to keep
learning and striving always the time.
