Your CSS file is generally well-structured, but there are a few improvements and corrections you could make for better performance, maintainability, and correctness:

Font-Face Declaration:

You have inconsistencies in your font-weight values. Ensure they match standard values: 100, 200, 300, 400, 500, 600, 700, 800, 900. You have some duplicate and incorrect entries, such as: Poppins-Light has font-style: italic. Poppins-Thin has font-weight: normal. Poppins-SemiBold has font-weight: semibold which is not valid. Use 600. Fix format syntax in the src attributes. Font-Face Example:

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-Black.ttf') format('truetype');
    font-weight: 900;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-BlackItalic.ttf') format('truetype');
    font-weight: 900;
    font-style: italic;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-Bold.ttf') format('truetype');
    font-weight: 700;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-BoldItalic.ttf') format('truetype');
    font-weight: 700;
    font-style: italic;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-ExtraBold.ttf') format('truetype');
    font-weight: 800;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-ExtraBoldItalic.ttf') format('truetype');
    font-weight: 800;
    font-style: italic;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-ExtraLight.ttf') format('truetype');
    font-weight: 200;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-ExtraLightItalic.ttf') format('truetype');
    font-weight: 200;
    font-style: italic;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-Italic.ttf') format('truetype');
    font-style: italic;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-Light.ttf') format('truetype');
    font-weight: 300;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-LightItalic.ttf') format('truetype');
    font-weight: 300;
    font-style: italic;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-Medium.ttf') format('truetype');
    font-weight: 500;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-MediumItalic.ttf') format('truetype');
    font-weight: 500;
    font-style: italic;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-Regular.ttf') format('truetype');
    font-weight: 400;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-SemiBold.ttf') format('truetype');
    font-weight: 600;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-SemiBoldItalic.ttf') format('truetype');
    font-weight: 600;
    font-style: italic;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-Thin.ttf') format('truetype');
    font-weight: 100;
}

@font-face {
    font-family: 'Poppins';
    src: url('assets/Poppins/Poppins-ThinItalic.ttf') format('truetype');
    font-weight: 100;
    font-style: italic;
}```
**
Media Queries:
**
Nested selectors within media queries (.header h1, .header p) might not work as intended. Use direct descendant selectors.
Media Query Example:

@media (max-width: 375px) { body > main { padding: 3em 1em; }

.header h1 {
    font-size: 1.3em;
}

.header p {
    text-align: justify; /* text-justify is not a valid CSS property */
}

.content {
    display: flex;
    flex-direction: column;
    row-gap: 3em;
}

}```

General Styles:

Use valid values for font-weight. Replace non-standard values like semibold with appropriate numerical values. Ensure consistent usage of CSS properties. General Example:

body {
    min-width: fit-content;
    height: auto;
    font-family: 'Poppins', sans-serif; /* Fallback font added */
}

body > main {
    display: flex;
    flex-direction: column;
    align-items: center;
    min-height: fit-content;
}

.header {
    display: flex;
    flex-direction: column;
    align-items: center;
    height: fit-content;
    color: var(--very-dark-blue);
    text-align: center;
    margin-bottom: 3em;
}

.header h1 {
    font-size: 2em;
    font-weight: 300; /* 'lighter' replaced with numeric value */
    letter-spacing: 1.5px;
}

.header p {
    font-size: 0.9em;
    font-weight: 700; /* 'bold' replaced with numeric value */
    margin-top: 0;
}

.content {
    box-sizing: border-box;
    margin: 0 auto;
    display: grid;
    grid-template-rows: repeat(4, 1fr);
    grid-template-columns: repeat(3, 1fr);
    gap: 2em;
    height: auto;
}

.footer {
    display: block;
    height: auto;
    font-size: 0.8em;
    font-weight: 700; /* 'bold' replaced with numeric value */
    text-align: center;
}

.footer a {
    color: var(--very-dark-blue);
    text-decoration: none;
}

.card {
    background-color: white;
    position: relative;
    max-width: 22em;
    min-height: 15em;
    padding: 1em 2em;
    box-sizing: border-box;
    border-radius: 5px;
    box-shadow: 0px 5px 10px var(--grayish-blue);
}

.card h2 {
    color: var(--very-dark-blue);
    font-size: 1.25rem;
}

.card p {
    color: var(--grayish-blue);
    font-size: 0.8em;
    font-weight: 700; /* 'bold' replaced with numeric value */
    line-height: 2em;
}

.card img {
    max-width: 20%;
    height: auto;
    position: absolute;
    right: 10%;
    bottom: 10%;
}

.left {
    grid-column: 1;
    grid-row: 2 / 4;
    border-top: 4px solid var(--cyan);
}

.top {
    grid-column: 2;
    grid-row: 1 / 3;
    border-top: 4px solid var(--red);
}

.bottom {
    grid-column: 2;
    grid-row: 3 / 5;
    border-top: 4px solid var(--orange);
}

.right {
    grid-column: 3;
    grid-row: 2 / 4;
    border-top: 4px solid var(--blue);
}```
