    What does CSS stand for?

    • A.

      Computer Style Sheets

    • B.

      Cascading Style Sheets

    • C.

      Creative Style Sheets

    • D.

      Control Style Sheets

    Correct Answer
    B. Cascading Style Sheets
    Explanation
    Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in HTML. It is responsible for the visual appearance of web pages, including layout, colors, fonts, and other design elements. CSS allows web designers to separate the structure and content of a webpage from its presentation, making it easier to maintain and update the design across multiple pages.

    What are the main differences between ID and Class

    • A.

      Classes are for use with spans and ID's are for use with DIVs

    • B.

      ID's are supposed to be only used once per page but Classes can be used multiple times per page, and one element can have more than one Class but should have only one ID

    • C.

      Classes should be used only once per page, but ID's can be used as many times as you like on one page

    • D.

      ID's are better than Classes

    Correct Answer
    B. ID's are supposed to be only used once per page but Classes can be used multiple times per page, and one element can have more than one Class but should have only one ID
    Explanation
    The main difference between ID and Class is that IDs are meant to be used only once per page, while classes can be used multiple times. Additionally, an element can have more than one class, but it should have only one ID. This is because IDs are used to uniquely identify an element, while classes are used to group multiple elements together. Therefore, the statement that IDs are supposed to be used only once per page and classes can be used multiple times per page, and an element can have more than one class but should have only one ID, accurately describes the main differences between ID and Class.

      6

    • B.

      12

    • C.

      9

    • D.

      14

    Correct Answer
    B. 12
    Explanation
    The Bootstrap grid system is based on 12 columns. This means that the layout of a webpage can be divided into 12 equal-width columns, allowing for easy and flexible positioning of elements. By using the grid system, developers can create responsive designs that automatically adjust to different screen sizes and devices. The 12-column grid system is a widely used standard in web development and provides a solid foundation for building responsive and visually appealing websites.

    In Bootstrap, content must be placed within...

    • A.

      Rows

    • B.

      Containers

    • C.

      Columns

    Correct Answer
    C. Columns
    Explanation
    In Bootstrap, content must be placed within columns. Columns are used to create a grid system in Bootstrap, allowing for the organization and layout of content on a webpage. By placing content within columns, it becomes easier to create responsive designs that adapt to different screen sizes and devices. Rows and containers are also important components in Bootstrap, but the content itself should be placed within columns to ensure proper alignment and structure.

      .container-width

    • D.

      .container-fw

    Correct Answer
    B. .container-fluid
    Explanation
    The correct class name to make a full width container in Bootstrap is ".container-fluid". This class is specifically designed to create a container that spans the full width of the viewport, adapting to different screen sizes and resolutions. Using this class ensures that the container will always fill the entire width of the screen, providing a responsive layout.

    In Adaptive Design, you build multiple versions of a website and use server side detection to then present custom code for that device or viewport size. Often having another domain just for your mobile experience like, m.domain.com

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    In Adaptive Design, multiple versions of a website are created and custom code is presented based on the device or viewport size using server side detection.

    What does this meta tag do?<meta name="viewport" content="width=device-width, initial-scale=1">

    • A.

      Tells the browser to look for media queries in the CSS file

    • B.

      Automatically makes a website responsive

    • C.

      Prevents browsers from scaling desktop websites on mobile

    Correct Answer
    C. Prevents browsers from scaling desktop websites on mobile
    Explanation
    The given meta tag, , prevents browsers from scaling desktop websites on mobile devices. By specifying the "width=device-width" property, it ensures that the website is displayed at the device's actual width, rather than being scaled down to fit the screen. This is important for maintaining the proper layout and design of the website on mobile devices. Additionally, the "initial-scale=1" property sets the initial zoom level to 100%, further preventing any scaling of the website.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Responsive design aims to provide an optimal viewing experience across different devices and screen sizes. One of the challenges in achieving this is finding a balance between the content needs for both mobile and desktop. Desktop sites typically have more space to accommodate elements like carousels, videos, parallax background images, and large blocks of text. Therefore, the statement that a big challenge with responsive design is finding a balance between the content needs for both mobile and desktop is true.

      Bootstrap 2

    • B.

      Bootstrap 3

    • C.

      Bootstrap 4

    Rate this question:

  • 21. 

    Which grid layout below is using Bootstrap 4 with flexbox?

    Correct Answer
    A.
    Explanation
    The correct answer is "Container > Row > Col". This layout structure is commonly used in Bootstrap 4 with flexbox. The "Container" class sets the maximum width of the layout and centers it on the page. The "Row" class is used to create horizontal rows within the container. The "Col" class is used to create columns within the rows, allowing for flexible and responsive layouts. The combination of these classes and the use of flexbox makes this grid layout the correct answer.

    Rate this question:

  • 22. 

    Flexbox is NOT a core CSS technology but a custom named component created by Bootstrap.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Flexbox is a core CSS technology that is used for creating flexible and responsive layouts. It is not a custom named component created by Bootstrap. Flexbox provides a set of CSS properties and values that allow developers to easily control the alignment, direction, and ordering of elements within a container. It is widely supported by modern browsers and is commonly used in web development to create dynamic and adaptive designs. Therefore, the statement that Flexbox is a custom named component created by Bootstrap is false.

    What are the three main elements of the Bootstrap grid listed in the proper order.

    • A.

      CRC = .col > .row > .container

    • B.

      GRC = .grid > .row > .col

    • C.

      CRC = .container > .row > .col

    • D.

      RC = .row > .col

    Correct Answer
    C. CRC = .container > .row > .col
    Explanation
    The correct answer is CRC = .container > .row > .col. In Bootstrap grid system, the container is used to contain and center the content. The row is used to create horizontal groups of columns. And the col is used to define the columns within a row. The proper order of these elements is container, row, and then col.

    Rate this question:

  • 24. 

    How is the .container-fluid class different from the .container class?

    • A.

      The .container-fluid class makes the container expand the full width of the browser

    • B.

      The .container-fluid class clears all floats and starts a new row

    • C.

      The .container-fluid class removes all horizontal padding so it touches the left and right edge of the browser window

    Correct Answer
    A. The .container-fluid class makes the container expand the full width of the browser
    Explanation
    The .container-fluid class is different from the .container class because it allows the container to expand the full width of the browser. This means that the container will stretch to fill the entire width of the browser window, without any horizontal padding. This is in contrast to the .container class, which has a fixed width and adds horizontal padding to the container.

    For each Bootstrap 4 grid row, the  number of columns has to equal ________

    Correct Answer
    12
    Explanation
    For each Bootstrap 4 grid row, the number of columns has to equal 12. This means that the grid system in Bootstrap 4 is divided into 12 equal columns, and when creating a row, the total number of columns within that row should be 12. This allows for flexible and responsive layouts, as the columns can be easily adjusted and rearranged based on different screen sizes and devices.

    What happens if your grid columns use just the .col class?<div class="container"> <div class="row"> <div class="col"> Column </div> <div class="col"> Column </div> </div> </div>

    • A.

      Each column will be full width and expand 100% horizontally.

    • B.

      Each column will wrap the content but be auto width

    • C.

      Grid columns without a set breakpoint width will automatically layout with equal widths. So in this example, 50%/50%

    • D.

      Since the Bootstrap 4 grid uses floats, each column will float left

    Correct Answer
    C. Grid columns without a set breakpoint width will automatically layout with equal widths. So in this example, 50%/50%
    Explanation
    The grid columns in this example will automatically layout with equal widths because they are using the ".col" class without any specified breakpoint width. This means that each column will take up 50% of the container's width, resulting in a 50%/50% layout.

    Correct Answer
    A. True
    Explanation
    Cards in Bootstrap 3 serve as a replacement for panels, thumbnails, and wells. They are designed to contain a group of content within a border and inner padding.

    • A.

      These classes will cancel each other out

    • B.

      Since p-0 is first it will override all of the other classes. So the heading will have 0 padding on all breakpoints.

    • C.

      0 padding on all breakpoints, 4 padding value on md breakpoint, then stop the padding from flowing to lg and xl

    Correct Answer
    C. 0 padding on all breakpoints, 4 padding value on md breakpoint, then stop the padding from flowing to lg and xl
    Explanation
    The spacing utility classes in the given code will result in 0 padding on all breakpoints, except for the md breakpoint where it will have a padding value of 4. The p-0 class will override all other classes and set the padding to 0 on all breakpoints. However, the p-md-4 class will then add a padding value of 4 specifically for the md breakpoint. The p-lg-0 class will stop the padding from flowing to the lg and xl breakpoints, effectively canceling out any padding on those breakpoints.

    • D.

      .justify-content-center

    Correct Answer
    C. .mx-auto
    Explanation
    The class ".mx-auto" would make this column centered. This class is used in Bootstrap to horizontally center a block-level element within its parent container. It sets the left and right margins of the element to "auto", causing it to be centered. In this case, applying the ".mx-auto" class to the column would center it within the parent container.

    In Bootstrap 4, 1rem = _____ ?

    • A.

      14px

    • B.

      15px

    • C.

      16px

    • D.

      20px

    Correct Answer
    C. 16px
    Explanation
    In Bootstrap 4, 1rem is equal to 16px. This means that if we set the font-size of an element to 1rem, it will be displayed with a font size of 16 pixels. Rem stands for "root em" and is a unit of measurement that is relative to the font-size of the root element (usually the element). Therefore, 1rem will always be equal to the font-size defined for the root element, which is typically set to 16px in Bootstrap 4.
