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 send "/posts" request, I receive a styled page.

Add Partials: Header and Footer

Partials are files or templates that we can write, then we can include in other templates.

Step One: Create new files

I create a new directory "Partials" and add two ejs files "header" and "footer" inside it.

Step Two: Write header

In the header file, I add the basic HTML <head>, <title>, <body> and <link> to the "app.css" file. Those tags are on the top of every HTML page.

Step Three: Write Footer

The footer is simple. It just includes the closing tag for body and html. I also add a simple paragraph on the top of closing tags.

Step Four: Add partials in each ejs template

Since "header" and "footer" files are created, I don't have to copy and paste each header and footer code in every template again and again.

I just need to write simple ejs tags to include the "header" and "footer" in the ejs template. That will make the code clean.

As the result, I send the "/wantto/workout" page, it shows title "Demo App", adds styles, and displays the footer message.

Seven Most Common jQuery Methods Last Part: ADD/REMOVE/TOGGLE CLASS()

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. I only want to change the first list item color and background by writing: $("li").first().toggleClas...

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...
