A They make tables responsive by stacking rows on small screens.

B They add colorful borders to make tables more attractive.

C They automatically sort table data alphabetically.

D They improve readability by reducing white space and fitting more data on screen.

Identify the error in this Bootstrap table code for compact style

This code tries to create a small Bootstrap table but has a mistake. What is the error?

Bootsrap

<table class="table small">
  <thead>
    <tr><th>Item</th><th>Price</th></tr>
  </thead>
  <tbody>
    <tr><td>Pen</td><td>$1</td></tr>
  </tbody>
</table>

A The <thead> tag cannot be used with Bootstrap tables.

B The table tag is missing the closing </table> tag.

C The class 'small' is not a Bootstrap table class for compact tables.

D The <tbody> tag should come before <thead>.

💡 Hint

Bootstrap uses a specific class name for small tables.

Bootstrap uses 'table-sm' to make tables compact, not 'small'. Using 'small' alone does not apply the compact style.

How to make a small Bootstrap table accessible?

You have a small Bootstrap table. What is the best way to improve its accessibility for screen readers?

Bootsrap

<table class="table table-sm">
  <caption>Product quantities</caption>
  <thead>
    <tr><th scope="col">Product</th><th scope="col">Qty</th></tr>
  </thead>
  <tbody>
    <tr><td>Notebook</td><td>5</td></tr>
  </tbody>
</table>

A Remove the <thead> section to simplify the table.

B Add <caption> describing the table content.

C Use only <div> elements instead of <table> for better accessibility.

D Add inline styles to increase font size.

💡 Hint

Think about how screen readers understand tables.

Adding a element provides a clear description of the table's purpose, helping screen reader users understand the data context.

Practice

1. What does the Bootstrap class table-sm do when added to a table?

easy

A. Makes the table smaller and more compact by reducing padding

B. Changes the table background color to gray

C. Adds borders around each table cell

D. Makes the table text bold and larger

Solution

1. Step 1: Understand the purpose of table-sm

   The table-sm class in Bootstrap reduces the padding inside table cells, making the table smaller and more compact.

2. Step 2: Compare with other options

   Other options describe unrelated styles like background color, borders, or text size, which table-sm does not control.

3. Final Answer:

   Makes the table smaller and more compact by reducing padding -> Option A

4. Quick Check:

   table-sm = smaller, compact table [OK]

Hint: Remember: 'sm' means small and compact table padding [OK]

Common Mistakes:

• Confusing table-sm with color or border classes
• Thinking it changes font size or weight
• Assuming it adds table stripes or hover effects

2. Which is the correct way to apply a small and compact style to a Bootstrap table?

easy

A. <table class='table compact'>

B. <table class='table table-small'>

C. <table class='table small-table'>

D. <table class='table table-sm'>

Solution

1. Step 1: Identify Bootstrap's official class for small tables

   Bootstrap uses table-sm to make tables small and compact, not table-small, small-table, or compact.

2. Step 2: Verify syntax correctness

   The correct syntax includes both table and table-sm classes inside the class attribute.

3. Final Answer:

   <table class='table table-sm'> -> Option D

4. Quick Check:

   Use table-sm with table class [OK]

Hint: Always pair table-sm with table class [OK]

Common Mistakes:

• Using incorrect class names like 'table-small' or 'compact'
• Forgetting to include the base 'table' class
• Misspelling the class name as 'table sm'

3. What will be the visual difference when rendering this table with Bootstrap classes?

<table class='table table-sm'>
  <tr><td>Item</td><td>Price</td></tr>
  <tr><td>Apple</td><td>$1</td></tr>
</table>

medium

A. The table cells have less padding, making the table more compact

B. The table text will be italicized

C. The table will have a blue background

D. The table rows will have alternating colors

Solution

1. Step 1: Understand the effect of table-sm on table cells

   The table-sm class reduces the padding inside each cell, making the table appear smaller and more compact.

2. Step 2: Check other options for unrelated styles

   Italic text, background color, or striped rows are not caused by table-sm but by other classes like table-striped or custom CSS.

3. Final Answer:

   The table cells have less padding, making the table more compact -> Option A

4. Quick Check:

   table-sm = less padding, compact table [OK]

Hint: Less padding means smaller, tighter table cells [OK]

Common Mistakes:

• Assuming table-sm changes text style or colors
• Confusing with striped or hover effects
• Expecting background color changes

4. You wrote this code but the table is not compact:

<table class='table small'>
  <tr><td>Name</td><td>Age</td></tr>
  <tr><td>John</td><td>30</td></tr>
</table>

What is the error?

medium

A. The table tag is missing a closing tag

B. The class should be table-sm, not small

C. The table rows need tbody wrapper

D. The table cells should use th instead of td

Solution

1. Step 1: Check the class name for compact tables

   The class small is not a valid Bootstrap class for tables. The correct class to make tables compact is table-sm.

2. Step 2: Verify other code parts

   The table tag is properly closed, tbody is optional, and td is valid for data cells. These are not errors causing lack of compactness.

3. Final Answer:

   The class should be table-sm, not small -> Option B

4. Quick Check:

   Use table-sm for compact tables [OK]

Hint: Use exact class table-sm, not 'small' [OK]

Common Mistakes:

• Using 'small' instead of 'table-sm'
• Thinking missing tbody breaks compact style
• Confusing td and th roles

5. You want a table that is small and compact but also has striped rows and hover effect. Which is the correct class combination?

hard

A. table table-small striped hover

B. table-sm table-striped table-hover

C. table table-sm table-striped table-hover

D. table compact striped hover

Solution

1. Step 1: Identify required Bootstrap classes

   Bootstrap requires the base table class plus modifiers like table-sm for small tables, table-striped for striped rows, and table-hover for hover effect.

2. Step 2: Check each option for correctness

   Only table table-sm table-striped table-hover includes all correct classes with proper prefixes. The other options miss the base table class or use invalid class names.

3. Final Answer:

   table table-sm table-striped table-hover -> Option C

4. Quick Check:

   Combine table with all needed modifiers [OK]

Hint: Always include base table class with modifiers [OK]

Common Mistakes:

• Omitting the base table class
• Using invalid class names like 'table-small' or 'compact'
• Forgetting to add hover or striped classes properly
