Solution retrospective


As a person who is new to coding, I would like advice to following questions:

  • What are some ways I could have made this solution more accessible?
  • Do you have any tips on how to analyze a design more accurately before replicating it in code?
  • What are some best practices to make my codes cleaner?

    Hey Christine, It looks good!...

    My suggestions:

    • Instead give each element padding: 15px; to align all at the same level, Give the container that contains all elements padding: 15px;.

    • Use REM for font size, It is a must for accessibility because px in some browsers doesn't resize when the browser settings are changed.

    See this article ---> CSS REM – What is REM in CSS?

    .card {
      width: 320px;  /* Chenged */
      height: 500px;
      background-color: var(--White);
      border-radius: 20px;
    
      padding: 15px;   /* <---- Add */
    }
    .card .image img {
      width: 100%;   /* Chenged */
      height: 288px;  /* Chenged */
      border-radius: 10px;   /* Chenged */
      /* padding: 15px;      <---- Remove */
    }
    .card .text {
      font-family: "Work Sans", sans-serif;
      text-align: center;
      /* padding: 0px, 30px, 20px, 30px;     <---- Remove */
    
      margin-top: 24px;   /* <---- Add */
    }
    .card .text h1 {
      /* font-size: 18px;      <---- Remove */
    
      font-size: 1.47rem;    /* <---- Add */
      font-weight: 700;
      line-height: 1.4;
    }
    
    

    Hope this is helpful to you... Keep coding👍

    Basically it is like this - * {margin: 0; padding: 0; box-sizing: border-box;}. Before writing the code you should help yourself with a graphics program, to see the dimensions and some spaces, I use Inkscape (free). For fonts, padding, marging it is best to use the units rem or em

How does the accessibility report work?

When a solution is submitted, we use axe-core to run an automated audit of your code.

This picks out common accessibility issues like not using semantic HTML and not having proper heading hierarchies, among others.

This automated audit is fairly surface level, so we encourage to you review the project and code in more detail with accessibility best practices in mind.

How does the CSS report work?

When a solution is submitted, we use stylelint to run an automated check on the CSS code.

We've added some of our own linting rules based on recommended best practices. These rules are prefixed with frontend-mentor/ which you'll see at the top of each issue in the report.

The report will audit all CSS, SCSS and Less files in your repository.

How does the HTML validation report work?

When a solution is submitted, we use html-validate to run an automated check on the HTML code.

The report picks out common HTML issues such as not using headings within section elements and incorrect nesting of elements, among others.

Note that the report can pick up “invalid” attributes, which some frameworks automatically add to the HTML. These attributes are crucial for how the frameworks function, although they’re technically not valid HTML. As such, some projects can show up with many HTML validation errors, which are benign and are a necessary part of the framework.

How does the JavaScript validation report work?

When a solution is submitted, we use eslint to run an automated check on the JavaScript code.

The report picks out common JavaScript issues such as not using semicolons and using var instead of let or const, among others.

The report will audit all JS and JSX files in your repository. We currently do not support Typescript or other frontend frameworks.
