FreeCodeCamp | FreeCodeCamp算法训练项目解答

I want my contact section of my page to have links to my social. I applied :hover to my span classes to make it move up by 5px. Although ALL of my links move down when i hover over the desired link... what did I do wrong can some one please help.. Code is below.

There is one project challenge on freecodecamp about building a calculator and I just managed to pass all the tests but when looking back on my code, the section dealing with the operations are barely readable. I've read some articles online regarding how to reduce the complexity of conditionals and the principles to keep in mind for more easy-to-understand logic.

However, figuring out the achievable logics for this task in javascript is quite challenging to me now. I was trying to meet two conditions with this section of code as follows:

User Story #13: If 2 or more operators are entered consecutively, the operation performed should be the last operator entered (excluding the negative (-) sign). For example, if 5 + * 7 = is entered, the result should be 35 (i.e. 5 * 7); if 5 * - 5 = is entered, the result should be -25 (i.e. 5 * (-5)).

User Story #14: Pressing an operator immediately following = should start a new calculation that operates on the result of the previous evaluation.

Here is the link to the page for this particular challenge and this is the link to the code I wrote by far.

Is there any tips and advice on refining the code or other approaches for coping with this part?

I am learning algorithms in Python right now. Are there websites where I can learn these algorithms "in the browser" with byte-size lessons, like Codecademy and Freecodecamp have, free or paid?

Im trying to replicate the freeCodeCamp Survey Form

When i use inline-block it only works only after .form-control input.

And I only want to use it for radio , but it seems like it doesn't work when I put [type="radio"] after .form-control input.

Can someone describe what is wrong? Thank you guys.

I would like to adjust the footer position in a shiny app. When the page content is shorter than the viewport, the footer should be at the bottom of the viewport. When the page content is longer than the viewport, the footer should be below the content. This post suggests how to usually implement it in CSS. This and similar solutions are commonly straightforward to use when writing the page's HTML code by hand.

There are discussions on footer positions in shiny and some of them manage to move the footer to the bottom. However, they fail to keep the footer from overlapping with the bottom of the page's main content, which requires shortening the main content's container.

Consider the following minimal working example:

I'm learning a bit of JavaScript, but I'm having hard time understanding the lesson on FreeCodeCamp about the recursion countdown (link).

In the lesson, there this initial example. But I'm confused on how it operates:

This error is showed up when I ran the code for an Arkanoid Game published on freecodecamp articles. I am not able to set up the configuration correctly for the game. I expected it to run the game but it didn't do the same. While debugging it kept throwing errors regarding its build. I have no idea as I have learned it online but this error is not getting resolve. I am attaching both the debugger image and the error image along with the log file text, where it showed the error. DEBUG CONSOLE

I cannot pass Story #5: "When I click a .nav-link button in the nav element, I am taken to the corresponding section of the landing page." I have all of my href attributes set to the corresponding id attributes and when i click on them they take me to the correct section of the page, but I am still failing this test... What am I Doing Wrong???

The code I wrote is below:

I have 2 accounts , one is for personal use and another one is for professional usage. Now to work with multiple github accounts I have to perform these steps ,

1. Generating the SSH keys
2. Adding the new SSH key to the corresponding GitHub account
3. Registering the new SSH Keys with the ssh-agent
4. Creating the SSH config File
5. One active SSH key in the ssh-agent at a time

Now the account that I am using for professional usage is shared with 5 more people , i.e we are using same credential.

Now my question is , If I perform those above tasks(1-5), then will they face any error while pushing or fetching repository? If yes then how to bypass the issue?

Thanks and regards
