The Basics of HTML and CSS – What You Need to Know

Before you begin learning HTML and CSS, you need to have a basic understanding of what you are doing. While the field is vast, it is best to start with the basics and build from there. There are many resources available for you to use for furthering your understanding of these technologies.

Structural elements

Whether you’re using HTML5 or older browsers, structural elements in HTML & CSS are essential to make your pages look great. Having a well-structured page will make it easier for people to navigate and search your site. In addition, it will be cleaner to edit. While CSS3 and HTML5 have many new features, there are still some things you’ll want to remember about HTML4 and its structural elements. For example, you’ll still want to use the div tag and the id and class attributes. However, only use them when they serve a specific role within a page.

The header element is used to provide introductory content and navigation aids. The head element falls within the HTML element and is very similar to the header. The head element also has a function, but it’s more of a general description of what the document is about.

Attributes

HTML attributes can be used to describe the appearance and behaviour of an element. Examples include href, lang, style, and src. Another popular attribute is the title, which provides additional information about an item. When the mouse is over an element, the value of the title attribute will be displayed as a tooltip.

Most of these attributes have two faces. The first face is used for the element’s width, while the second face is for the height. Both of these properties can be used to specify the height of an element, although CSS’s height property is preferred.

Line break elements

Line break elements are a common feature of HTML and CSS that enable a user to create additional lines between paragraphs or blocks of text. Without these breaks, the text would appear oddly formatted. Line break elements can be added to HTML with the BR tag. This tag acts as the equivalent of the carriage return key on the keyboard. Note that HTML will ignore the character ‘r’ as a line break.

HTML has several ways to add a line break. One way is to use the white-space property, which inserts a new line before the element. Other methods include using the display property to begin the element on a new line and using the carriage return character and pseudo-elements to add a line break.

Colours

There are two primary methods for specifying colours in HTML and CSS. One is called a colour name, and the other is called a colour number. HTML colours are a little trickier to remember than CSS colour names, so they are not recommended. Modern browsers support around 140 different colour names.

HTML and CSS support 16 different colour names, as well as 147 different colour names for CSS3. These colour names are specified using hexadecimal colour numbers (base 16). The hexadecimal system is broken into three groups of two digits, each describing the percentage of Red, Green, and Blue that is present in a colour. The values range from 00 to FF.

Mobile compatibility

There are a few things you can do to make your website compatible with mobile devices. While you shouldn’t completely ignore the limitations of mobile browsers, you should take into account the limitations of their memory, processing power, bandwidth, and viewport size. One way to make your website more mobile-friendly is to split the content into separate views. You can also simplify your content and interface.

First, make sure your website is designed to look good on all devices. Screen sizes on mobile devices are much smaller than those of desktop computers. This means that a website designed for desktops may not load properly or look as good on these smaller screens. To fix this problem, you should restructure your website to optimize for the different sizes and screen resolutions of these devices.

JavaScript

JavaScript is a markup language similar to HTML, but it’s more complex. It first appeared in beta form in 1995 and is now supported by all major web browsers. Most websites use JavaScript to alter website content and make it behave in certain ways. Common uses for JavaScript include confirmation boxes and calls-to-action. It’s also useful for adding new identities to information on a page.

When used in conjunction with HTML, JavaScript allows website developers to create dynamic HTML pages that can alter the user interface. It can also alter HTML elements through selectors and can change almost any attribute or content. In addition, it can interact with the browser and server and even generate a page from logic.
