Web design is the process of creating a website that is both visually pleasing and easy to use. It involves a combination of color theory, layout, and branding.
What the user sees is created using a coded language like HTML and Cascading Style Sheets (CSS). Web developers then take the designer’s work and put it into code to create a functioning site. Click Here to learn more.
HTML is a computer language used to create web pages. It describes how a page should be displayed on an internet browser and can be written in almost any text editor.
The structure of HTML pages is comprised of several elements, including the head>, body>, and div> elements. Each of these sections contains information about the page and allows for easy styling.
Each section is nested, which means that it can contain other HTML tags to add further functionality. Nested elements can also include a link, which lets visitors click through to another page or section of text.
Using the right HTML element can make it easier for people with disabilities to access a website. If a screen reader or audio browser can correctly ascertain the structure of a document, it will not waste the user’s time reading out repeated or irrelevant information.
Some of the more popular HTML elements include the h1> tag, which is for headings; h2> tags, which are for subheadings; h3>-h6> tags, which are for smaller headings within body text; and p>, which is used to define paragraphs of text.
In addition to these basic HTML elements, there are several specialized elements for specific purposes. For example, the img> element is used for displaying images on web pages and enables designers to create scalable vector graphics (SVG). Other specialized HTML elements include the canvas> element, which is used to draw a graphical image on the screen; the section> element, which is used to divide a webpage into different sections; the nav> element, which is used to create navigation menus; and the audio> element, which is used to describe MP3 files, WAV files, and OGG files in HTML.
CSS, short for Cascading Style Sheets, is a language used in web design to change the appearance of a page. This includes adjusting text size, fonts, layout, and colors. It also controls how a website looks on different devices, including mobile phones and tablets.
When a web browser loads a page that contains both HTML content and CSS styling, it first converts the content into a document object model (DOM). Each piece of HTML, text, and other data is assigned a DOM node.
The DOM is a tree-like structure that contains nodes for each element in the markup language, such as HTML. Once all of the elements are assigned a DOM node, the browser will display them to users.
Once the document has been displayed, it can be resized according to the screen size of the device or by another reference point, such as a printer. Responsive web design uses flexible layouts and images to automatically adjust the appearance of a page to suit the screen size.
Until responsive web design was developed, the styling of a website could cause errors when it was resized for a device with a different screen size. This caused a lot of confusion for the developers as they worked to create a new style for each size.
To avoid this, a CSS rule is defined using selectors. These are key-value pairs that match tags and attributes in the markup to apply a style to a particular element.
A style can be applied to a single element or a group of elements, such as all of the paragraphs on a web page. The rules are usually saved as external.css files and can be accessed by all pages on the site.
