You are creating a form that asks a user to enter their phone number. The form must be submitted only if the phone number field is not empty and matches the format 111-444-7777. Which markup should you use?

• A. < input type= " tel " name= " phone " pattern= " [0-9]{3}[0-9] {3}[0-9]{4} " >
• B. < input type= " tel " name= " phone " pattern= " [1]{3}-[4] {3}-[7]{4} " required >
• C. < input type= " tel " name= " phone " pattern= " [0-9]{3}-[0-9] {3}-[0-9]{4} " required >
• D. < input type= " tel " name= " phone " maxlength= " 12 " required >

You need to identify the form elements.
Move the appropriate semantic elements from the list on the left to the correct locations on the right.
Note: You will receive partial credit for each correct response.

Explanation:
Club Points indicator # < meter >
Order Status group title # < legend >
Choose delivery frequency options # < datalist >
Shipping Information group box # < fieldset >
Displayed shipping information # < output >
The correct semantic elements are selected according to the role each visible form component performs. The Club Points visual indicator represents a scalar measurement within a known range, so it corresponds to < meter > . The bordered Order Status section is a grouped form region, and the caption displayed on the border is a < legend > , which labels a fieldset-style group. The delivery frequency control shows an editable input with selectable predefined values, which is the purpose of < datalist > : it supplies suggested options for an associated input without forcing the user to choose only from the list. The Shipping Information section is visually and semantically a grouped set of related form information, so the surrounding grouping element is < fieldset > . The displayed shipping address is generated or presented as result-style information rather than typed directly in that location, which matches < output > . fieldset groups related controls, legend labels that group, meter displays a bounded measurement, datalist provides input suggestions, and output displays calculated or resulting information.

You need to create the layout shown, which defines five content areas:
* Logo and page title
* Menu
* Main content area
* Additional content area
* Copyright and contact information
You define the following classes:

• A. .grid-container { display: grid; grid-template-areas: " heading heading heading heading heading heading
  " " menu content content content right right " " menu contact contact contact contact contact " ; grid- gap: 10px; background-color: orange; padding: 10px;}
• B. .grid-container { display: grid; grid-template-rows: " heading heading heading heading heading heading
  " " menu content content content right right " " menu contact contact contact contact contact " ; grid- gap: 10px; background-color: orange; padding: 10px;}
• C. .grid-container { display: grid; grid-template-columns: " heading heading heading heading heading heading " " menu content content content right right " " menu contact contact contact contact contact " ; grid-gap: 10px; background-color: orange; padding: 10px;}
• D. .grid-container { display: grid; grid-template-columns: 33% 33% 33%; grid-template-rows: 300px
  500px 300px; grid-gap: 10px; background-color: orange; padding: 10px;}

You define the Pet class as follows:
class Pet {
constructor(name, breed) {
this.name = name;
this.breed = breed;
this.show = function() {
var text = " < p > Your pet ' s name is " + name + " . The pet ' s breed is " + breed + " . < /p > " ; return text;
};
}
}
You need to derive a Dog class from the Pet class.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.

Explanation:
First blank: class Dog extends Pet {
Second blank: super(name, breed);
The correct syntax for deriving one JavaScript class from another is extends, so the derived class declaration must be class Dog extends Pet {. This creates Dog as a subclass of Pet, allowing Dog instances to inherit members defined by the Pet constructor, including name, breed, and the show() function assigned inside the parent constructor. Inside a derived class constructor, super() must be called before using this. The call super (name, breed); invokes the parent Pet constructor and passes the values required to initialize the inherited name and breed properties. Pet(name, breed); is incorrect because a class constructor cannot be invoked like a normal function. Pet.constructor(name, breed); is also incorrect because it does not call the parent constructor for the current instance. After super() runs, the Dog constructor can safely assign subclass-specific properties such as price and gender.

You define the following layout:
< !DOCTYPE html >
< html >
< head >
< style >
section {
display: flex;
align-items: center;
flex-wrap: wrap;
min-height: 200px;
width: 700px;
background: linen;
}
section p {
flex: 1;
min-width: 200px;
padding: 20px;
}
< /style >
< /head >
< body >
< h2 > Exhibits to visit at the zoo < /h2 >
< section >
< p style= " order: 3 " > Lions < /p >
< p style= " order: 4 " > Tigers < /p >
< p style= " order: 2 " > Bears < /p >
< p style= " order: 1 " > Zoo Trip < /p >
< /section >
< /body >
< /html >
For each statement about the markup shown on the left, select True or False.

Explanation:
The paragraph containing the text Tigers will display first.
False
The section p CSS refers to the parent flexbox container.
False
When the paragraphs have a width less than 200px, the last paragraph will wrap to the next line.
True
The parent flexbox container is the section element because it has display: flex;. The paragraphs inside the section become flex items. The display order is controlled by each paragraph's inline order value, and flex items are laid out from the lowest order value to the highest. Therefore, Zoo Trip with order: 1 displays first, followed by Bears, Lions, and finally Tigers; the statement that Tigers displays first is false. The selector section p does not refer to the parent flexbox container. It targets paragraph elements inside a section, meaning it styles the flex items, not the flex container. The container itself is targeted by the section rule. The final statement is true in intent because flex-wrap: wrap; allows flex items to move to a new line when they cannot fit in the available row. Since each paragraph has min-width: 200px, items are prevented from shrinking below that minimum and wrapping occurs when available space is insufficient. References/topics:
