Prerequisites:
Before starting this tutorial, you should have a basic understanding of HTML and CSS. Additionally, you will need a code editor such as Visual Studio Code or Sublime Text to write and save your code.
Source Code
Step 1 (HTML Code):
To kick things off, let's establish the foundation by setting up the HTML structure. Follow these steps:
- Create a container div for the spreadsheet.
- Set up rows and columns using HTML elements.
Let's break down the code:
1. <!DOCTYPE html>: This declaration defines the document type and version of HTML being used (HTML5, in this case).
2. <html lang="en">: The root element of the HTML document. The lang attribute specifies the language of the document (English).
3. <head>: Contains meta-information about the HTML document, such as character set, viewport settings, title, and linked stylesheets.
- <meta charset="UTF-8">: Specifies the character encoding of the document as UTF-8.
- <meta http-equiv="X-UA-Compatible" content="IE=edge">: Instructs Internet Explorer to use the latest rendering engine.
- <meta name="viewport" content="width=device-width, initial-scale=1.0">: Defines the viewport settings for responsive design.
- <title>MS Excel Clone</title>: Sets the title of the web page.
- <link rel="stylesheet" href="styles.css">: Links an external CSS stylesheet named "styles.css" to the HTML document.
4. <body>: Contains the content of the HTML document that will be displayed in the browser.
- <div class="main-content">: The main container for the entire content.
- <div class="title">Book1 - Excel</div>: Represents the title of the Excel-like application.
- <div class="menu-bar">: Contains a menu bar with various menu items.
- Several <div> elements with <span> elements inside represent different menu options like File, Home, Insert, etc.
- <div class="icon-bar">: Contains different sets of icons grouped under specific categories like Clipboard, Font, Alignment, Number, Styles, and Cells.
- Each set contains various icons (<div class="icon">) representing different functionalities, such as paste, cut, copy, font settings, alignment, number format, styles, and cell operations.
- <div class="cell-content">: Contains a section with "fx" and an empty <div>.
- <div class="cells">: Represents the grid of cells in the Excel-like application.
- <div> and <input> elements create a grid of cells with letters for columns (A, B, C, ...) and numbers for rows (1, 2, 3, ...).
- Several <input class="cells__input"/> elements: Represent individual cells in the grid.
- <input class="input__explanation" value="Part of the CSS Grid Collection ??"/>: Represents an input field with an explanation.
- <div class="input__see-more">: Contains a link to an external source (a CodePen collection).
- <div class="input__sm-1">, <div class="input__sm-2">, <div class="input__sm-3">: Contain links to social media profiles (Twitter, GitHub, Dribbble).
Step 2 (CSS Code):
Now, let's make your spreadsheet visually appealing with CSS. Here's how:
- Apply basic styling to the container and cells.
- Use CSS grid for layout management.
Let's go through each section of the CSS code and understand what each part does:
1. * selector with box-sizing: border-box;:
- This sets the box-sizing property to border-box for all elements. It means that padding and border values will be included in the element's total width and height.
2. body selector:
- Defines styles for the entire document body.
- Set the background color to white (#fff).
- Specifies the font family as "Noto Sans" and a generic sans-serif as a fallback.
- Sets the text color to a dark gray (#444).
- Sets the font size to 14 pixels.
3. aside.context selector:
- Targets an <aside> element with class "context."
- Align text in the center.
- Sets text color to a slightly darker gray (#333).
- Defines a line height of 1.7 for better readability.
4. aside.context a selector:
- Targets anchor (<a>) elements within the "context" aside.
- Removes text decoration (underlines).
- Sets text color to a darker gray (#333).
- Adds padding above and below the anchor text and creates a bottom border with a dashed line.
5. aside.context a:hover selector:
- Applies styles when hovering over the anchor links.
- Change the bottom border to a solid line.
6. aside.context .explanation selector:
- Target elements with class "explanation" within the "context" aside.
- Sets a maximum width of 700 pixels.
- Centers the element horizontally (margin: 0 auto).
- Adds top margin of 6em.
7. footer selector:
- Styles for the footer of the document.
- Centers text horizontally.

- Removes text decoration.
- Creates circular buttons with a border, white background, and dark gray text.
- Adds some spacing around the buttons.
9. footer a:hover selector:
- Applies styles when hovering over the footer buttons.
- Changes the background to a slightly transparent white.
10. footer a .icons selector:
- Styles an icon element within the footer buttons.
- Adds margin to vertically center the icon.
- Sets the font size to 20 pixels.
11. .main-content selector:
- Targets the main content section of the page.
- Applies a grid layout with specified rows and heights.
- Uses min-height: 100vh to ensure that the content occupies at least the full viewport height.
- Sets max-width to 100%.
12. .main-content > div selector:
- Targets immediate child div elements within the main content.
- Sets max-width to 100% for these child divs.
13. .title selector:

- Sets a green background color (#217346).
- Align text in the center both horizontally and vertically.
- Text color is white.
14. .menu-bar selector:
- Defines styles for a menu bar.
- Uses a grid layout with 10 columns, each containing max-content width.
- Adds padding, grid gap, and a light gray background.
15. .menu-bar div:nth-child(2) span selector:
- Styles a specific span within the second child div of the menu bar.
- Creates an underline effect with a green color (#217346).
- Sets font weight to 700.
16. .cell-content selector:
- Styles for a cell content section, possibly within a grid.
- Sets a light gray background and border.
- Uses a grid layout with two columns, the first being 50px wide and the second occupying the remaining space.
17. .cells selector:
- Styles for a cells section, part of a grid-based layout.
- Uses a grid layout with multiple columns and rows.
- Sets a background color and defines spacing.
18. .cells__spacer, .cells__alphabet, .cells__number, .cells__input selectors:
