HTML – Hypertext Markup Language:
All critical website content should be added
to the website using a markup language
such as HTML.
Proper comment section should be used
before writing any code because it will help

us in identifying why this code has been
written and what is the use.
Always add “alt” attributes to images
because it will help when an image for
some reason cannot be displayed Use
lower case element and attribute names.
Use correct document type – Always
declare the document type as the first line
in your document.
Close all HTML elements and quote the
attribute values.
Do not add blank lines & indentation
unnecessarily.
Avoid code lines over 80 characters.

CSS – Cascading style sheets:
Presentation of the website content should
be defined by a styling language such as
CSS.
Use simple syntax for linking to style sheets

(the type attribute is not necessary) with
proper comments.
Place the opening bracket on the same line
as the selector
Use one space before the opening bracket
Use two spaces for indentation
Use semicolon after each property-value pair,
including the last
Only use quotes around values if the value
contains spaces
Place the closing bracket on a new line,
without leading spaces
Avoid lines over 80 characters
New file should be used for creating CSS

Class:
If there are multiple elements on a single
web page and that need to be styled then
we use classes. For example, let’s say that
you want give a redirect a particular button
to some site or at new page or at pressing

the button it’s color should be change. So
for modifying colors & redirecting page to
some link we use classes and for that you
could add a class to each of those button or
the container holding the buttons.

div.cities {
background-color: black;
color: white;
margin: 20px 0 20px 0;
padding: 20px;

CSS/JavaScript custom file:
We are using a framework using different
libraries then we should not change the
library files instead of that we should create
another file and then do the customization.
For example, in bootstrap, we are using a
navbar and it contains its own CSS file
navbar-default and we are asked to change
in that particular file so for that we’ll create
a new custom CSS file.
Bootstrap library file:

.navbar-default {
text-decoration: none;
background color: #1A237E;

Custom file
.navbar-default {
background color: #5aD782;
color: #ff00ff;
}
CSS According Framework:
A framework is defined as a package made
up of the structure of files and folders of
standardized code (HTML, CSS, JS
documents etc.) which can be used to
support the development of the website, as
a basis to start building a site. So as to use
framework we should place the library
along with proper commenting.

Single Page CSS:
For every page, there should be separate
CSS file and it should contain the
information about that particular page only.
For example, let’s say there are four pages
(Home, About Us, Products Contact Us) so

for each and every page there should be
separate CSS file with proper commenting
and relevant names.
Code Re-usability:
Code which shares a very similar or
identical structure should be written in such
a way that it can be used further. The aim
of code reusability is to provide a common
structure so that developers don’t have to
redo it from scratch and can reuse the code
provided. In this way, code reusability
allows us to cut out much of the work and
save a lot of time.
Code Check:
Before submitting the code it should be
reviewed and checked properly maintaining

the above guidelines rules. It will help
understand the third party user easily
without facing any difficulties.
