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 the image fit the screen very well no matter how big or small of the window. 


Then, we set the float property value. Float is used to display the image side by side. We want the images float to the left. 


As we can see, all the images are displayed together on the left of page, and the page looks very crowed. We want to add some space between each image. Therefore, we need to calculate the margin value

Since the each image width is 30% of the page, so three images are occupied 90% of the page. In the other word, there is 10%  space left. 

If we want each image has equal space, we will need to do some math. Each image has two margins-left and right, and we have three image, so there are 6 margins total. Then we use 10% divide 6, the result is 1.66%.



Step Three: Set The Paragraph  Property Values

We want have a name of this gallery, so we add a short paragraph on the top of the page. We set the font-family, font-size and font-weight, and all letters are uppercase. 


We want the content margin to be the same as the image margin, so we set the same margin and width value for the paragraph content.

We want add an underline between the paragraph and images, so we only add an orange border on the bottom of the paragraph box. 

At last, it would be better to have some space between the content and images, so we use set padding-bottom (inner margin of the box) value to be 20px. 

The final outcome:

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 ...
