海外TECH	DEV Community	How to make fully responsive modern portfolio using pure HTML, CSS and JS.	https://dev.to/kunaal438/how-to-make-fully-responsive-modern-portfolio-using-pure-html-css-and-js-1p65	How to make fully responsive modern portfolio using pure HTML CSS and JS Hello Today we ll see how to make a fully responsive modern portfolio using pure HTML CSS and JS No other library You learn to create responsive design you ll learn about CSS pseudo elements You ll learn about nodemailer to make a working contact form And much more To see demo or you want coding tutorial with explanation You can watch the tutorial below Video TutorialI appreciate if you can support me by subscribing my youtube channel So without wasting more time let s see how to code this CodeBefore we start writing our code Let s see its folder structure And yes it is a nodeJS app because we want working mailing system and only servers can send mail not client side browser As you can notice we have project js file This files contain our project data Having a project data make easier for you to add and delete or edit any project you want Let s see its data structure let projects name project one tags javascript fullstack ui ux backend image project png name project two tags javascript fullstack image project png more You can see we have project name its tags and image path This way we can easily handle our projects without editing any code So let s start by initializing NPM NPM initInside your root directory outside public folder open your command prompt or terminal and run npm init cmd This will initialize NPM to your projects Now run this command to install these libraries npm i express js nodemon nodemailer dotenvexpress js is to create a servernodemon is to run server continuouslynodemailer is to send mailsdotenv is for making environment variable We ll use this store our email id and password outside of server After done installing libraries Let s make some changes in package json Open it And change its scripts data scripts start nodemon server js Then make server js file inside your root directory not in public folder Open it Server jsStart by importing libraries packages const express require express const path require path const nodemailer require nodemailer const dotenv require dotenv Setup dotenv so we can access environment variable dotenv config Then store your public folder path to a variable and make server let initialPath path join dirname public let app express Now use app use method to setup middlewares app use express static initialPath app use express json They both are important express json will enable form data sharing and express static will set public folder as a static path After this make home route And send index html file app get req res gt res sendFile path join initialPath index html And at last make server listen on port app listen gt console log listening So our server is done for now Let s run the server by running npm start cmd on your terminal Now let s start working on portfolio PortfolioOpen index html and write basic HTML structure Then link style css and app js to the file After that make navbar lt navbar gt lt nav class navbar gt lt h class brand gt logo lt h gt lt div class toggle btn gt lt span gt lt span gt lt span gt lt span gt lt div gt lt ul class links container gt lt li class links item gt lt a href class link active gt home lt a gt lt li gt lt li class links item gt lt a href project section class link gt project lt a gt lt li gt lt li class links item gt lt a href about section class link gt about lt a gt lt li gt lt li class links item gt lt a href contact section class link gt contact lt a gt lt li gt lt ul gt lt nav gt And give it some styles margin padding box sizing border box html scroll behavior smooth body width position relative background ddd color fff font family

before seperator before content position absolute bottom left transform translateX width px height px border radius background fff link active after seperator after content position absolute bottom px left width height px background fff NoteYou can see scroll behavior given to html If you don t give this you ll not be able to get smooth scrolling effect you can also see seperator element in the styles but don t worry we ll create this later OutputNow create header section lt home section gt lt section class home gt lt div class hero content gt lt h class hero heading gt lt span class highlight gt hi lt span gt i am john lt h gt lt p class profession gt web developer lt p gt lt p class info gt Lorem ipsum dolor sit amet consectetur adipisicing elit Consequatur odit in laudantium

position absolute top left width height background eee z index transform skewX deg profession after content position absolute top left px width px height px background eee info line height px margin bottom px btn padding px px text decoration none border radius px background ff color fff text transform capitalize border none OutputGreat now make about section lt about section gt lt section class about id about section gt lt h class heading gt about lt span class highlight gt me lt span gt lt h gt lt p class sub heading gt Lorem ipsum dolor sit amet consectetur lt p gt lt div class seperator

col after content position absolute top px right px width px height px background fff transform origin right transform rotate deg about image border radius px box shadow px px rgba about para font size rem font weight line height px margin bottom px OutputAnd now create skills section Add this structure inside about section lt section class about id about section gt previous elements lt h class heading gt languages and framework i know lt h gt lt div class seperator gt lt div gt lt div class skill container gt lt div class skill card style bg f gt lt p class skill gt HTML lt p gt lt div gt

div gt lt div class skill card large style bg edfb gt lt p class skill gt Much More lt p gt lt div gt lt div gt lt section gt You can notice we have style bg value to skill card element What this is doing is it is setting up different bg CSS variable for different elements So this way we can add same effect with different colors skill container position relative margin top px display grid grid template columns repeat fr grid gap px skill card height px border radius px border px solid text align center position relative cursor pointer transition s skill font size rem color line height px skill card hover background var bg skill card hover skill color fff skill card large grid column span Outputbackground color is showing on hoverNow let s create project section In project section first make filter buttons lt project section gt lt section class project id project section gt lt h class heading gt Project lt span class highlight gt s lt span gt lt h gt lt p class sub heading gt Lorem ipsum dolor sit amet consectetur lt p gt lt div class seperator gt lt div gt lt div class filters gt lt button class filter btn active id all gt all lt button gt lt button class filter btn id javascript gt javaScript lt button gt lt button class filter btn id ui gt ui ux lt button gt lt button class filter btn id backend gt backend lt button gt lt button class filter btn id fullstack gt fullStack lt button gt lt div gt lt section gt The id attribute in filters will help us in filtering the projects project section project contact position relative padding px vw filters width fit content display block margin px auto filter btn padding px px border radius px border none text transform capitalize margin px px cursor pointer filter btn active background ff color fff OutputAnd now just for styling purpose make single project card lt div class project container gt lt div class project card gt lt img src img project png alt gt lt div class content gt lt h class project name gt project one lt h gt lt span class tags gt javascript lt span gt lt div gt lt div gt lt div gt project container width display grid grid template columns repeat fr grid gap px project card position relative cursor pointer display block project card img width height object fit cover project card content position absolute top left width height background rgba display flex justify content center align items center transition s text transform capitalize opacity project name font weight font size rem text align center tags position absolute bottom px opacity width project card hover content opacity project card hide display none OutputContent is showing on hoverNow you can comment the project card lt div class project container gt lt lt div class project card gt lt img src img project png alt gt lt div class content gt lt h class project name gt project one lt h gt lt span class tags gt javascript lt span gt lt div gt lt div gt gt lt div gt And let s make project card dynamically But before doing that Add you project js file before app js file Otherwise you ll not be able to access project data lt script src project js gt lt script gt lt script src app js gt lt script gt Now open app js And before making project card Let make the links toggle active class For that code this linksconst links document querySelectorAll link links forEach link gt link addEventListener click gt links forEach ele gt ele classList remove active link classList add active And after doing that we are good to go on project cards So code this creating dynamic project cardconst projectContainer document querySelector project container projects forEach project gt projectContainer innerHTML lt div class project card data tags all project tags gt lt img src img project image alt gt lt div class content gt lt h class project name gt project name lt h gt lt span class tags gt project tags lt span gt lt div gt lt div gt You can see we are just selecting the project container and then looping through the data to make cards OutputGreat now make filter button functional filtersconst filters document querySelectorAll filter btn filters forEach filterBtn gt filterBtn addEventListener click gt let id filterBtn getAttribute id let projectCards document querySelectorAll project card projectCards forEach card gt if card getAttribute data tags includes id card classList remove hide else card classList add hide filters forEach btn gt btn classList remove active filterBtn classList add active In above code we are just adding click event to filter button and toggling some elements class So out project section is fully done Now make contact form lt contact form gt lt section class contact id contact section gt lt h class heading gt Contact lt span class highlight gt me lt span gt lt h gt lt p class sub heading gt Lorem ipsum dolor sit amet consectetur lt p gt lt div class seperator gt lt div gt lt div class contact form gt lt div class name gt lt input type text class first name

margin px text transform capitalize resize none message height px contact form name display flex justify content space between name input width margin contact form btn display block margin auto cursor pointer footer footer width height px text align center background color ff text transform capitalize line height px OutputNow let s make mail route inside server jsapp post mail req res gt const firstname lastname email msg req body const transporter nodemailer createTransport service gmail auth user process env EMAIL pass process env PASSWORD const mailOptions from sender email to receiver email subject Postfolio text First name firstname nLast name lastname nEmail email nMessage msg transporter sendMail mailOptions err result gt if err console log err res json opps it seems like some error occured plz try again else res json thanks for e mailing me I will reply to you within working days This is a way to send mail with nodemailer There are some thing you have to notice process env EMAIL amp process env PASSWORD this keyword give you access to environment variable but we haven t made any variable for that Create a file in your root directory env Name should be the same Open it and type this EMAIL your emailPASSWORD your email s passwordSo now if you understand process env will access these variables from amp to parameters In the code above I have not entered my email s but in order to make mail work you have to give email id as their params You can give same email id to both So out server is fully done Now make contact form working contact formconst contactBtn document querySelector contact btn const firstName document querySelector first name const lastName document querySelector last name const email document querySelector email const msg document querySelector message contactBtn addEventListener click gt if firstName value length amp amp lastName value length amp amp email value length amp amp msg value length fetch mail method post headers new Headers
