Exploring HTML and Tailwind CSS: A Stylish Grid

In this blog post, we'll dissect a piece of HTML code along with its corresponding Tailwind CSS classes to create a stylish grid layout. This code snippet is designed to display three numbered elements in a centered, responsive grid. Let's break it down step by step. 

<div class="flex h-full w-full flex-wrap justify-center bg-[white]">
    <div class="m-[5px] grid flex-[0_1_150px] place-items-center rounded-2xl border border-solid border-[color:var(--green--b)] bg-[color:var(--green)] p-4 text-[2rem]">
    1
    </div>
    <div class="m-[5px] grid flex-[0_1_150px] place-items-center rounded-2xl border border-solid border-[color:var(--green--b)] bg-[color:var(--green)] p-4 text-[2rem]">
    2
    </div>
    <div class="m-[5px] grid flex-[0_1_150px] place-items-center rounded-2xl border border-solid border-[color:var(--green--b)] bg-[color:var(--green)] p-4 text-[2rem]">
    3
    </div>
</div>

HTML Structure

  1. Container Div (<div class="flex h-full w-full flex-wrap justify-center bg-[white]">):
    • flex: Specifies that the container should use a flexbox layout.
    • h-full: Sets the height to 100% of the parent's height.
    • w-full: Sets the width to 100% of the parent's width.
    • flex-wrap: Allows flex items to wrap onto multiple lines if needed.
    • justify-center: Centers the flex items along the horizontal axis.
    • bg-[white]: Sets the background color to white.
  2. Grid Items (1, 2, 3):
    • Each of the three div elements represents an item in the grid.
    • They have similar classes with slight variations.
    • m-[5px]: Adds a margin of 5 pixels around each item.
    • grid: Specifies that this element should use grid layout.
    • flex-[0_1_150px]: Utilizes a responsive sizing class from Tailwind CSS, which sets the flex property to 0, 1, and a minimum width of 150 pixels.
    • place-items-center: Centers the content both horizontally and vertically within the grid item.
    • rounded-2xl: Applies a rounded border with a radius of 2xl (extra large).
    • border: Adds a border to the element.
    • border-solid: Sets the border style to solid.
    • border-[color:var(--green--b)]: Specifies the border color using a custom CSS variable (--green--b).
    • bg-[color:var(--green)]: Sets the background color using a custom CSS variable (--green).
    • p-4: Adds padding of 4 units (16 pixels) around the content.
    • text-[2rem]: Sets the font size to 2 rem units.
    • The numbers 1, 2, and 3 represent the content within each grid item.

Tailwind CSS Classes Summary

  • m-[5px]

    Sets a margin of 5 pixels around an element.

  • grid

    Enables grid layout for an element.

  • flex-[0_1_150px]

    Controls flexbox behavior responsively. In this case, it sets the flex property to 0 1 150px, meaning it won't grow, will shrink if necessary, and has a minimum width of 150 pixels.

  • place-items-center

    Centers the content both horizontally and vertically within a grid or flex container.

  • rounded-2xl

    Applies a rounded border to an element, giving it a rounded appearance. The 2xl indicates an extra large border radius.

  • border

    Adds a continuous line border around an element. By default, the border will be the same color as the text color.

  • border-solid

    Sets the border style to solid, creating a continuous line border around the element.

  • border-[color:var(--green--b)]

    Sets a custom border color using a CSS variable named --green--b.

  • bg-[color:var(--green)]

    Sets a custom background color using a CSS variable named --green.

  • p-4

    Adds padding of 4 units (16 pixels) around the content within an element. This creates space between the content and the element's border.

  • text-[2rem]

    Sets the font size to 2 rem units. REM units are relative to the root element's font size. In this case, it sets the text size to be twice the size of the root font.

These Tailwind CSS classes, when used together, create a visually appealing and well-structured grid layout with specific styling properties applied to each element.

Conclusion

This HTML code, combined with Tailwind CSS classes, creates a visually appealing grid layout. It's responsive, making it suitable for various screen sizes. The custom CSS variables (--green and --green--b) used for colors allow for easy customization. This code snippet can be a great starting point for building similar grid-based designs.
