contains vital information the user needs and links to access other pages owned by the website Developers aim to create a website that induces visitor use and attracts organic growth This can be achieved by building a unique landing page optimized for a good user experience At the end of this article you should be able to create a landing page with HTML and CSS The text editor used for illustration in this article is VS Code Other text editors and IDEs perform similar tasks Examples include Bracket Notepad Sublime Text and others This is what a VS Code interface looks like An excellent landing page houses the information needed by the internet user to determine if it suits their needs or not The items that can be found on a landing page include the logo title the navigation bar that bears links to access other embedded pages forms to be filled by the site visitors and CTAs call to action Below is an example that explains the illustration given above Why the Need to Start with HTML HTML Hypertext Markup Language is the bedrock of any website and so it will provide the website structure This tutorial will help ease the difficulties of comprehending it Getting Started with HTML Start by creating an HTML file This is done by creating a new folder in your text editor and giving it a name of your choice After that you are to choose the programming language of your choice Type in HTML and Click Enter This file is to be saved with a name ending with html index html was used here Remember to save your file by using ctrl S as your work progress may disappear if you don t The HTML file should contain all of the raw text needed for the website We will start with the heading It is the first item the website visitor will get to see so it should be conspicuous eye catchy and easy to understand This can be the name of your business the title of a paper or the overall leading text of the information you wish to divulge On the text editor the HTML elements are represented with tags and the texts are embedded within them A glance at this guide from w schools will provide more insight on tags in HTML and their uses Headings are written in the text editor using the lt h gt lt h gt tags This is an example from the sample website illustrating how tags can be used lt h gt Welcome to The Little Bookshop lt h gt A quick trick to getting the layout for the document is typing HTML It supplies the layout of the webpage as shown below lt DOCTYPE html gt lt html gt lt head gt lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset UTF gt lt meta http equiv X UA Compatible content IE edge gt lt meta name viewport content width device width initial scale gt lt link rel stylesheet href style css gt lt title gt The Little Bookshop lt title gt lt head gt lt body gt lt body gt lt html gt The main text is written in the lt body gt The next step to add is the navigation bar It holds other links that lead the site visitors to other pages hosted on the website This is included in the body of the page A navigation bar should look like this in the HTML document lt div class nav gt lt ul gt lt li gt lt a href home gt Home lt a gt lt li gt lt li gt lt a href about us gt About Us lt a gt lt li gt lt li gt lt a href shop gt Shop lt a gt lt li gt lt li gt lt a href cart gt Cart lt a gt lt li gt lt li gt lt a href my account gt My Account lt a gt lt li gt lt li gt lt a href book reviews gt Book Reviews lt a gt lt li gt lt li gt lt a href contact us gt Contact Us lt a gt lt li gt lt ul gt lt div gt The body of the website comes next This is where the main information to be shared with the site visitors is put in The illustration used in this article is the website of a bookshop and so the text will come from there lt h gt Welcome to The Little Bookshop lt h gt lt img src shelves jpg alt Bookstore gt lt h gt lt p gt The Little Bookshop believes in the power of books and the ability they have to transport you to places that seem impossible to reach lt br gt lt br gt Although we have store outlets located in different surbubs of the country we pay special attention to our online community that do not have access to these spaces lt br gt lt br gt Take your time and scour our shelves you ll be sure to find something that is to your liking lt br gt lt br gt We are deeply interested in the welfare of our customers and their literary tastes which is why we stock up books of all genres and authors at affordable prices for you lt p gt For your website you can add other perks you feel are necessary like a flash sales tag discount or announcement In the website used for example a feedback form was included for the bookshop visitors to drop their comments and feedback like this lt div class container gt lt h

lt textarea gt lt input type submit value Submit gt lt form gt lt div gt lt h gt lt div gt lt body gt lt html gt lt head gt lt html gt Result Styling With CSSSince HTML provides the basic structure of the website it is imperative to add some style to the page to make it unique and outstanding The website used here is that of an online bookshop so we would style it to look like one There are different ways of styling a website inline CSS internal CSS and external CSS External CSS has proven over time to be the most efficient as it makes your source code more organized and prevents the site from lagging As the name implies it is written on a separate interface from the HTML file saved as style css and contains all the styling for the website It is added to the HTML file with a link lt link rel stylesheet href style css gt It is put in between the lt meta name gt and the lt title gt of the document The page is styled in segments from the navigation bar down to the feedback form Some of the stylings affects the whole document such as the addition of background color or image background image This was used in the styling of the sample website although in a peculiar fashion In this case it was embedded in the HTML document lt h gt Welcome to The Little Bookshop lt h gt lt img src shelves jpg alt Bookstore gt lt h gt This led to the landing page having the image of a bookstore as the background image Other images can be used to replace this too Styling the navbar Add a black background colour to the navigation bar ul list style type none margin padding overflow
