Bootstrap Project Study: Create A Fancy Image Gallery in Details


I have shared how to apply Bootstrap code to create Nav-bar, Jumbotron, and Grid System in previous posts, so today I am going to use all my bootstrap learning to create a Image Gallery.



This is also a Udemy course project, so some image links are provided by instructor. I would like to share the project process here.

Add Bootstrap CSS & Java Script Links

I start to create a HTML page and link to the Bootstrap CSS code. At the bottom of <body>, I also add the Java Script and J Query links, so it will make sure the page is following the certain rule.


Create A Jumbotron

 I apply the Jumbotron code in the HTML, and add h1 header as "The Image Gallery" and a short paragraph to describe what this site is about.


By the way, just make sure the Jumbotron code is inside the "container", so everything will be moved to the center of the page.

Add A Nav-Bar

I just copy my old nav-bar code from previous Nav-bar exercise, but I make two changes. 
  • In the first <nav> element class attribute value, I change "navbar-default" to "navbar-inverse". It will give a black nav-bar. (To be honest, I prefer the default one. The instructor let us to try this way, it is worth to learn.)
  • Inside the <a> element, I edit the website name "Image Gallery Exercise"



The result:


Add Image Link In The Grid System

It' s time to add images in the grid system. For large size device, I would like to show three images per row, so each image will take 4 columns. As I shrink to the medium size, I want two images per line, so each image takes 6 columns.


In order to make all the image fit in the same shape, the instructor taught us to use "thumbnail" class value. 


Then, I make six copies of the code, and edit the image links. Since I want all the images align with the Jumbotron, I move the grid codes inside the "container".




Add Camera Icon

The instructor also show us how to add icon on the HTML. I insert the camera icon code from bootstrap components in front of "The Image Gallery" text. 


The result:


Make Our Own CSS Style

I want to add some space between the nav-bar and jumbotron, so I add some top-padding value.


The result:


Then I can change the jumbotron text color and navbar background color.


The result:



Test The Nav-bar

Finally, I need to test whether the nav-bar work. I shrink the window to the small size, the nav-bar is hided in the hamburger icon. As I click the icon, all the content shows up. 


The final image gallery page:

Intermediate Express.js: How To Add Styles & Partials in EJS File?

So far, we only have simple HTML tags and ejs tags in each ejs file. Every template page has no style at all. And the basic HTML header and footer are also missing. Today, I learned how to add styles and partials in ejs file. Link Style Step One: Touch a Separate CSS file I create a new directory "Style" under the "EJSDemo" directory, then I add a new CSS file "app.css" inside "Style" folder. Step Two: Add app.use(express.static()) in the app.js I add app.use(express.static("style")) in the "app.js". This will tell Express.js to serve the content of "Style" directory. Step Three: Write styles in CSS file I simple give body an orange background color and set text color to be grey. Step Four: Link to CSS file in the EJS file I just add <link> tag to link the "app.css" file on the top of the h1 tag in each ejs template. As the result, when I run the app and...

Intermediate Express.Js: Write Conditions and Loops In The EJS (study note)

We continue to use the app.js which we have build to be the study example. In the last post, we only add a simple EJS tag <%= thingVar %> inside h1 tag. This will match the "thing" to any "thing" request from the user. If Statement Today, the course shows us to write a simple if statement in the EJS file. I learn to apply it to my own app. In the if statement, if users send"/wantto/workout" request, the page will show a new content "Good Idea!". We wrote the if statement in the "diet.ejs" file, and we add "<% %>" tags around the code. We have to wrap every line of JavaScript anytime JavaScript starts and ends. Moreover, you may see there are two types of ejs tags here: <%= %> The one with equal sign. According to the course, when we add equal sign, the value that is returned inside of the tag will be rendered to the HTML page. it will be added to the HTML. For example, if we write ...

Authentication Project: Secret Page App Part One (Set up & Create User Model)

So far we only write the RESTful routes to send request and redirect to the related page, but we haven't do anything about authentication. If we can sign up, login, and log out, it will make our app more meaningful. Therefore, the course shows us how to create a secret page app, which will allow us to sign up, login to a secret page, and logout. Since it requires so many pieces, I will divided this project into three parts: set up & create user model, sign up, and login/logout. In this post, I am going to show all the set up process. Set Up Step One: Install packages The first thing we are going to do to create a folder "Auth", and inside of "Auth", we need to create another folder "AuthDemo". Then we cd (change directory) to "AuthDemo". Now we can set up the actual application structure by installing a few packages: passport, passport-local, passport-local-mongoose, mongoose, express, ejs, body-parser, and express-session....
