💡 Hint

Common Mistakes

Using input type "text" instead of "password" for passwords.

Forgetting to add the "required" attribute if the field must be filled.

The icon is "lock", the input type for passwords is "password", and adding "required" makes the input mandatory.

2. Which is the correct way to add a Bootstrap icon inside a button?

B. Search

C. Search

D. Search

Solution

1. Step 1: Identify Bootstrap icon syntax

   Bootstrap icons use <i> tags with classes like "bi bi-search".

   <button><i class="bi bi-search"></i> Search</button> uses <i> with correct classes; others use wrong tags or methods.

3. Final Answer:

   Bootstrap icons use <i> + bi classes = A [OK]

Hint: Use <i> tag with 'bi' classes for Bootstrap icons [OK]

   The icon inside .input-group-text appears on the left side inside a styled box next to the input.

3. Final Answer:

   An email input with an envelope icon on the left inside a styled box -> Option A

4. Quick Check:

  <i class="bi bi-search"></i>Search
</button>

C. Button tag should be <div>

D. Icon tag should be <span>

Solution

1. Step 1: Check icon and text spacing

   The icon and text run together without space, making them look joined.

2. Step 2: Confirm correct classes and tags

   Icon class "bi bi-search" and <i> tag are correct; button tag is correct.

3. Final Answer:

   Missing space between icon and text -> Option A

Solution

1. Step 1: Understand Bootstrap input groups

   To add an icon inside input on the right, wrap input and icon in .input-group.

2. Step 2: Place icon after input inside .input-group-text

   Placing icon after input inside .input-group-text aligns it on the right side and makes it clickable.

3. Final Answer:

   Wrap input and icon in .input-group with icon inside .input-group-text placed after input -> Option C

4. Quick Check:

   Right icon in input = input-group + input-group-text after input [OK]

• Trying to put icon inside placeholder
• Adding icon tag inside input element (invalid)
• Placing button outside input group losing alignment
