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...

Add, remove and toggleClass is also a very common way to manipulate style. .addClass() and .removeClass() I add two class selector in the style tag. Class one is to change text color to be green, and class two is change both text and background color.  Now I refresh the page and change h1 text to green by using addClass() method: $("h1").addClass("one") .  If you want to remove the style, you can change it to removeClass("one"). I do the same thing to the list. I change the list color and add a background color by adding the class two style value: $("li").addClass("two") . .toggleClass()  According to jQuery, toggerClass method can add or remove one or more classes from each element in the set of matched elements, depending on either the class's presence or the value of the state argument.

Intro to Backend: Is Browser The Only Place To Send HTTP Request?

Today,  I begin to learn the second part of web develop course: backend. Frontend is the stuff that we can see and interactive with, such as HTML, CSS, and JS. We can type our code, style our page, or write some function to make interaction. However, backend is everything else. For example, we type Target web address in the Internet Browser. As we hit "enter", there are a few steps to go through: 1. The HTTP request is sent to a particular server's IP address. 2. The server figures out what to send us 3. It sends a HTTP response back to us Those process we are hard to see, and it happens in less than one second. The instructor said that the browser is not the only place to send the HTTP request, and there are so many choices out there. In this learning course, we are going to use Postman App . Postman allows us to make HTTP requests and viewer responses. It is really for developers to understand how things are working or debug something. In the P...
