Project Study: Four Steps To Create A Tic Tac Toe Box

Today I am going to apply CSS box into a Tic Tac Toe table. And this is the assignment from the course.


Step One: Create A HTML Table

The Tic Tac Toe is a table contains three rows and three columns.


So the table page looks like:


You can't see the table because two reasons:

1. I didn't put any table data in the <td> elements, so it is an empty table.
2. I didn't add border in the CSS.

Step Two: Set Basic Text and Table Properties 

I start to move the header from the page left to the center, so I set the "text-align" property to be center.

Then I  set the table margin as auto and set each td width and height to be 100px.


As the result, the table get bigger, but it is still invisible without adding borders.



Step Three: Use Class Selector to Add Vertical Border

When I was doing this assignment, I did very well on the first two steps, but I got stuck on this step.

How to add the right border on each table data box? I tried to add border on table, but it didn't seem right. I even tried to use the nth-of-type selector to select each single box, but it was still wrong. I was so struggled, so I had to watch the solution video.

The course instructor told us to add "class" in the HTML and set all the vertical and horizontal value. The second cell of each row will have a left and right vertical border, and the second row will have a horizontal top and bottom border.


In the CSS, I set the class selector ".vert" border-left and border-right to be a black solid border.


The result shows the left and right border on the second  table column.


Step Four: Use Class Selector to Add Horizontal Border

The final step is to add the horizontal border for the second row of the table. We only set the top and bottom border.


The final result:


After this exercise, I realized that the hardest part is not about writing those code, but is about connecting all the code in a logical way.

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...

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...

Intermediate CSS: Three Steps To Create A Photo Gallery

I have seen many image blogs these years. People love to post their photos online to express life and feeling.  Image is powerful because it could bring a visual story to audience. People can see what you see, and may be feel the same way as you feel, too. If we want to build our own photo gallery, what should we do? Luckily, the boot-camp instructor just showed me how to use HTML and CSS to create a simple photo gallery.  I would love to share my study note here. (p.s. all the image links are provided by Udemy course instructor) Step One: Add Image Links on HTMLPage The instructor provides all the image links. All we need to do is add those links inside the <img> tag. Without CSS, the page will looks like this: they are not organized, and sizes are different, too. Step Two: Set Image Property Values We set the width of each photo the same value which is 30%, so there will be three images per line. The percentage value can help...
