<h2>Introduction to the course</h2><p>Cascading Style Sheets (CSS) is a style sheet language that holds website presentations on their shoulders by completing HTML with a wide range of styling options. CSS is considered a rule-based language. But what does that mean? It means you&#x27;re in charge of making that will be applied to elements on your web page.</p><h2>Who is this course for?</h2><p>CSS described Web Page presentation. Most, ending towards all, websites use CSS, so if you&#x27;re an aspiring web designer or web developer then you&#x27;re exactly where you need to be.</p>

<h2>What does this lesson cover?</h2><p>In CSS developers will bump into the term &quot;viewport&quot;, which indicates the part of the website, which is visible in the browser window.</p><p>In this lesson, we&#x27;ll be covering the term viewpoint thoroughly, with theoretical examples paired with practice-oriented lessons that will lead to lesson quizzes that aim at putting the developers&#x27; knowledge to practice.</p>

Background

<h2>What does this lesson cover?</h2><p>It&#x27;s time to include CSS into HTML, but how? There is no one solution that works for all HTML documents, in this lesson we&#x27;ll be contrasting three methods in depth, and they are Inline Styles, Embedded Style Sheets, and External Style Sheets.</p><p>As the name entails, External Style Sheets require importing from an external source, so we&#x27;ll dedicate a separate lesson to explaining how and when to do so.</p>

Style Sheets

<h2>What does this lesson cover?</h2><p>The term &quot;Media Queries&quot; is widely used in CSS for web page development.</p><p>Media queries allow you to customize the presentation of your web pages. This lesson aims at expanding the definition of media queries and put them into use.</p><p>By &quot;putting them into use&quot; we mean implementing them in code and reviewing their behavior.</p>

Media Queries

<h2>What does this lesson cover?</h2><p>The CSS float property specifies whether a box should float or not. Elements that come after the floating element will flow around it. The clear property specifies which sides of an element&#x27;s box other floating elements are not allowed.</p><p>In this lesson, we&#x27;ll be referencing how and what it takes for elements to float and the clear property</p>

Float

<h2>What does this lesson cover?</h2><p>CSS transitions allow animate a property from the old value to the new value smoothly over time.</p><p>In this lesson, we expand on how exactly transitions are added with supporting code examples that depict them in a more understanding way.</p><p>We&#x27;ll also be referencing keywords such as Multiple Transitions, and Additional Transitions.</p>

Transitions

<h2>What does this lesson cover?</h2><p>The word &quot;padding&quot; can be defined as the space between the border and the element content.</p><p>CSS generates padding with the help of the background color of the element in question. This lesson depicts how that takes place with supporting properties that are clearly depicted in code examples for better understanding.</p>

Paddings

<h2>What does this lesson cover?</h2><p>The newer version of CSS– CSS3, allows developers to create color gradients.</p><p>Gradients are a smooth transition between two or more colors. There are two ways to style CSS Gradients and expanding on those methods is the focal point of this lesson. We&#x27;ll define them separately, nd include in-depth information on each of them with the added help of code examples and lesson quizzes to support their main idea.</p>

Gradients

<h2>What does this lesson cover?</h2><p>As all programming languages have their own syntax, CSS is no different. The two main parts of CSS syntax/structure are one or more than one declarations and a single selector.</p><p>This lesson will expand on the usage of the two, and thus move onto a whole other concept that is apart of CSS syntax and the syntax of many other programming languages called comments.</p>

Syntax

Lesson Challenge

<h2>What does this lesson cover?</h2><p>CSS offers a wide range of properties that are typically used to align elements on a given web page.</p><p>For example, a given text inside the block-level elements can be aligned by initiating the text-align property.</p><p>Additionally, we&#x27;ll be working towards Center Alignment, Aligning with Position, and Left and Right alignments.</p>

Alignment

<h2>What does this lesson cover?</h2><p>The newer version of CSS: CSS3, allows transitions to be in control of how animations work and offers time with keyframe-based animations that allow developers to specify the changes in CSS properties over time as a set of keyframes, like flash animations.</p><p>In this lesson, we&#x27;ll learn how to create animations, the concept of keyframes, and additional properties.</p>

Animations

<h2>What does this lesson cover?</h2><p>The border properties allow you to define the border area of an element&#x27;s box. CSS offers various properties to style borders that you can bump into on many web pages.</p><p>We&#x27;ll expand on the border-style property that sets the style of a box&#x27;s border, the border-width property to specify the width of the border area, and finally the border-color property that sets the border color.</p><p>This lesson will expand on all the mentioned properties with syntax and structure definitions.</p>

Borders

<h2>What does this lesson cover?</h2><p>The newer version of CSS– CSS3, provides several properties for styling the font of the text.</p><p>We&#x27;ll be employing the font-family property to take full advantage of those methods.</p><p>We&#x27;ll get into all the specifics of fonts including Font Size, Font Wright, and Font Style.</p>

Fonts

<h2>What does this lesson cover?</h2><p>In this lesson, we&#x27;ll be going over one of the two core aspects of CSS syntax– selectors.</p><p>We&#x27;ve referred to selectors in the past lesson, however, the importance of selectors entails an additional reference. </p><p>We&#x27;ll further expand on the types of selectors, they are the Universal Selector, the Type Selector, the Id Selector, and the Class Selector. We&#x27;ll thus compare and contrast the types.</p>

Selectors

<h2>What does this lesson cover?</h2><p>In this lesson, we&#x27;ll be referencing the last component of the Box Model: Margins.</p><p>The margin properties allow you to set the spacing around the border of an element&#x27;s box. This lesson expands on their syntax and behavior in code.</p><p>Developers can additionally specify the margins for the individual sides of an element, this is another topic of this lesson.</p>

Margins

<h2>What does this lesson cover?</h2><p>The newer version of CSS– CSS3, allows developers to define of various text styles such as alignment, spacing, decoration, transformation, and others.</p><p>We&#x27;ll be referencing and putting to use the main text properties in this lesson.</p><p>The properties that we&#x27;ll be expanding on the furthest are the text-decoration property, the text-alignment property, and the text-transformation property. </p>

Text

<h2>What does this lesson cover?</h2><p>This lesson introduces another CSS concept called CSS units. CSS units refer to values that properties accept. </p><p>This lesson opens up the brackets of Units in CSS by expanding on Relative Length Units and Absolute Length Units.  These keywords will also be equipt with their definitions.</p>

Units

<h2>What does this lesson cover?</h2><p>The newer version of CSS– CSS3, allows developers to style links in each state.</p><p>Styling links indicates the modification of its color, and the removal of the default underline. </p><p>Both of the mentioned actions will be referenced in this lesson with their corresponding and supporting properties. We&#x27;ll depict the usage of the syntax of the said properties in code and provide lesson quizzes to test your knowledge on the manner,</p>

Links

<p><strong>The CSS selectors </strong>are used to select the elements you want to style. Selectors are the part of CSS rule set.</p>

<p>You can use CSS selectors to select HTML elements according to its <strong>id, class, type, attribute</strong> etc.</p>

<p>There are no selectors or combinators to select parent items, siblings of parents, or children of parent siblings.</p>

Universal Selector

<p>The universal selector is used with an asterisk <samp><strong><code>*</code> </strong></samp>character. It selects all the elements on the pages. This is very useful when you want to remove default margins and paddings from the elements.</p>

It&#x27;s not recommended to use the universal selector, since this selector matches every element on a web page that puts too much unnecessary pressure on the browsers.

Write Missing

Type Selectors

<p><strong>Type selectors </strong>target all instances of the element in the document with the corresponding element type name. Type selectors can be namespaced when developers implemented <strong><samp>@namespace</samp></strong>. This is usually executed when handling documents possessing numerous namespaces.</p>

<p>In the above example, we apply <strong><samp>color </samp></strong>and<strong><samp> text-align</samp></strong> properties to all paragraph elements in the document.</p>

Fill Missing

<p>Apply the style to all<strong> paragraphs </strong>in the document.</p>

Id Selectors

<p>The <strong>ID selector</strong> finds an element with a unique ID attribute and applies CSS rules to it.</p>

<p>The <samp><strong>id</strong> </samp>selector is defined with a hash sign <strong><samp># </samp></strong>immediately followed by the id value. An example of the id selector in use is given in the following code snippets below:</p>

<p>Write a style with an <strong>id </strong>selector named <strong>&quot;label&quot;</strong>.</p>

Class Selectors

<p>The Class Selector (<strong><samp>.class</samp></strong>) retrieves finds and styles HTML elements with specific <samp><strong>class</strong> </samp>attributes.</p>

<p>It&#x27;s defined with a period sign (<samp><strong>.</strong></samp>) immediately followed by the class value.</p>

<p>The above style rule renders the text in blue of every element in the document that has a <strong><samp>class </samp></strong>attribute set to <strong><samp>blue</samp></strong>.</p>

<p>Developers can specifically pinpoint the HTML elements that need to be affected by the class. This is executed by calling the <strong>element name</strong>, the period character (<strong><samp>.</samp></strong>) and the name of the <strong>class</strong>.</p>

<p>Write a style rule that applies to all elements with a <strong><samp>red</samp></strong> class attribute.</p>

class vs id

<p>You may ask what&#x27;s the difference between CSS <strong><samp>class </samp></strong>and <strong><samp>id </samp></strong>selectors?</p>

<p>The main difference between CSS class and ID is that ID selectors have to be used once in an HTML document. It means that individual elements must all have unique IDs. However, you can use class repeatedly in an HTML document. Therefore, you can add CSS rules to more elements with class selectors.</p>

Grouping Selectors

It is possible to shorten your code while applying the same style to several selectors.

You can group them into a comma-separated list to minimize the code in your style sheet.

<p>Create a style rule group that apples to <samp><strong>h1</strong></samp>, <samp><strong>h2</strong></samp>, and <samp><strong>h3 </strong></samp>type of elements.</p>

<h2>What does this section cover?</h2><p>This section expands on the basic concepts of CSS. This in now way indicates that the lesson is easy to cover. The fact of the matter is that some surface-level concepts correspond with the fundamentals of CSS.</p><p>We&#x27;ll be covering concepts like Style Sheets, Selectors, Units, etc. So the focus will be on the overall syntax of CSS.</p>

Basics

Styling

<h2>What does this section cover?</h2><p>The Box Model in CSS The consists of a box that serves as a wrap on every element in HTML. The wrap consists of paddings, borders, and margins paired with content.</p><p>This section expands on each element of the Box Model and defines that with the help of properties, as each method has more than one property.</p>

<h2>What does this section cover?</h2><p>Creating effects with CSS entails the usage of the following: Opacity, Shadows, Transitions, and Animations.</p><p>Each of these concepts in CSS have supporting properties that help in implementing the specified effect.</p><p>The focal point of this section is learning how to add the effect related proerties and initiate them properly while taking advantage of all they have to offer.</p>

Effects

<h2>What does this section cover?</h2><p>CSS page layout strategies allow developers to take elements incorporated in a web page and control where they&#x27;re positioned.</p><p>These techniques comprise the display, position, float, and alignment.</p><p>Each of the above-mentioned keywords presents its very own properties that help the development of the page layout.</p><p>This section focuses on addressing those properties (the properties are not limited to one per keyword, some keywords may have multiple properties), their usage, and behavior in code.</p>

Layout

<h2>What does this section cover?</h2><p>Responsive web design in CSS indicates resizing, hiding, or changing the location of the content to make it look more flattering on the user&#x27;s screen (on the web page).</p><p>This section covers every property, and technique that&#x27;s needed to achieve responsiveness.</p><p>We&#x27;ll be addressing terms and keywords like viewport, grid layout, and media queries.</p>
