This part doesn’t seem to be making a difference in the sizing to me. I am still not able to see the impact of setting the widths to min and max. I mean, I get the concept and it is a great one, but I am unable to see it making any difference. So tell me how will I be able to get to see that.



Is it standard to use the pixel unit when setting the minimum and maximum widths while using percentages to set the regular widths?

try to change 200px to 300px-500px, and then resize the browser window, I promise you gonna see the difference.


Hi, can I ask how to define which values to use for the min-width and max-width properties i.e. what drives the choice of values and are there any predefined values for specific devices? Thanks!

True, 400px worked for me, I would suggest codecademy to update the tutorial to put min-width of 400px so everyone can see the difference.

According to the lesson we use px in this case to ensure hard limits on the dimensions of the elements.

Can I know please how can I get such ruler on MAC OS or any alternative please?

I simply use the dev tools to inspect the box model of the <p> elements (specifically, their widths)

Codecademy instructed us to give the <p> elements a min-width property of 200px. Even if we don’t really see a big visual difference, these dimensions are the ones that make the web page look cleaner one most screen sizes. If you want to actually see a difference, use your browser’s dev tools to inspect the <p> elements’ box model

When you get onto media queries, you’ll see that there are some famous screen sizes. However, even if you know the width of a screen, you can still modify the widths of your elements to match your preferences (there aren’t any pre-defined widths for elements).

This lesson states:

Note : The unit of pixels is used to ensure hard limits on the dimensions of the element(s).

However, I don’t really get it. When I developed web pages in the past, I set most sizing properties (box model properties, font-size) using the rem unit. This means that if the user changes the default font size in his browser preferences, not only will the actual text adapt to these changes, but the whole web page will also get sized according to the user preferences. What about min-width and max-width? What happens if we set it using rem or px?
