The web was born decades ago and although it has grown and evolved into what it is today, the underlying principles remain the same. This is a sorted resource of web-related terms to get you up to speed.

The aim is that you will get a better understanding of the technical terms of the web and learn the meaning.

Browser – A web browser is the program you use to access websites. Web browsers are built and maintained by independent companies such as Google, Microsoft and Mozilla.

You are using a web browser to access this post. The most common web browsers are Chrome, Firefox, Safari and Edge.

Domain name – A domain name is part of what you type into a web browser to access a website. It is like a unique name tag for your business to identify you online. For example

The domain name is directly after the https://www part. and finishes at the end of the domain extension such as Everything after that is related but not considered the domain name. Go to what is a domain name to learn more.

URL – Stands for Uniform Resource Locator. Fortunately we don’t need to remember it and it is often just called a web address. A URL is the direct path to a page on your website. For example, a URL to our Brisbane web design service is It points directly to that page. All pages on your website has a unique URL that you go to to access it.

Web hosting – Website hosting is the computer server that stores all the files that make up your website. Your domain name gets configured to point to the location this server is connected to on the internet. When you access your website, the files are being sent to you from your web hosting.

People often think of your data being in the cloud but in reality it sits in tiny servers in cool dark rooms like this.

Every website that exists online is hosted on website hosting somewhere around the world. Web3 provides managed WordPress hosting and can setup and migrate everything needed for you to get your website online.

Cache – A web cache is a type of technique used by web browsers and website servers to temporarily store webpages and other website media to speed up access to it again in the future. It also helps to prevent web hosting lag. The downside is if new information has updated on the website, the cache needs to be purged and re-created. If your website has aggressive caching then new information may not be immediately seen by your website visitors. Here is a simple technique you can use to clear your browser cache.

Refresh – This may refer to a website refresh or it may refer to a browser refresh.

If it is a website refresh then that is the process of redesigning your websites look and feel. Web3 redesigns websites here. A website refresh involves planning, strategy, design, development and management to ensure a successful outcome for your business.

A browser refresh means to reload the page. If your website has a page that has new information published to it, the browser needs to be refreshed/reloaded to see the newest changes.

Screen shot – A screenshot is an image taken directly of the screen of your computer. Your computer has built in capabilities of taking a screenshot.

If you are on Mac, you press, [command]+[shift]+[4] keys together and then click and drag where you want the screenshot to be.
If you are on Windows, you press the [windows]+[shift]+[s] keys together and then click and drag where you want the screenshot to be. Some keyboards also have a [PrtScn] key (in between the [F12] and [Scroll Lock] keys) that can be used to take screenshots.

Responsive Wireframes

Prototype – A website prototype is a mockup of what a website will look like when it is made into a website.

A prototype can be anything from a scribble on a piece of paper or it can be a high-fidelity designed mockup with images and text in place which will be almost identical to the real thing.

We have tried and tested a number of prototype apps and use, and Adobe XD.

Web3 Logo
The Web3 Favicon

Favicon – A favicon is a 256 pixel (or smaller) image used as an icon to identify your site in the web browser. You will see the favicons next to the page title tab at the top of your page.

Navigation – Website navigation is the menus you see on your web page. The most common place for navigation is at the top of the website in the header next to the website logo.

You may also have page navigation throughout the page on your site, in the sidebars or in the footer.

An example of a websites header with the logo, page navigation on hover and search button

Header – The header is usually a small section at the top of your website that displays your branding, logo and main heading navigation. The header is generally consistent across all pages on your site.

website footer example

Footer – The footer is a small section at the bottom of your website that displays navigation and other relevant information necessary for your website visitors. You may find contact/subscribe forms or other widgets like a social media feed.

Captcha – Captcha is a challenge-response test to determine if an action on a website like sending a contact message was triggered by a human or a computer. Captcha stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”. You will see Captcha fields at the bottom of forms and greatly helps to reduce spam and automated bots.

Captcha fields create a negative user experience for legitimate users. Because of this and lots of people getting frustrated by having to fill out these fields, Captcha fields have improved where you simply tick a checkbox. If it thinks you are a robot then the captcha fields will appear.

Breadcrumb – Is a list of links acting as a trail from the homepage to the currently viewed page. It is a simple way to improve accessibility for your users allowing them to navigate through the structure of your site. A breadcrumb navigation has special code embedded to help search engines better understand the structure of the site.

HTML Sitemap – A HTML sitemap is a page on your website which lists all the pages on your website. It us used for users to be able to find a particular page if they need to. It is like a table of contents. A HTML sitemap should not be confused with an XML sitemap.

XML Sitemap – An XML sitemap is like a HTML sitemap but made for search engines. It is not meant to be user friendly and is written in XML markup for search engines to understand.

404 – When someone goes to a page on your site that doesn’t exist, your website hosting server will return an error. There are many types of error codes depending on what the error is. 404 is the error code for when a page does not exist.

Users can get a 404 error from typing the page incorrectly or they can get an error if the page has been removed. A special page dedicated to 404 errors can be included on your website. They will provide information to the user and direct the user to similar or other relevant pages. A 404 page might also include a search form.

.jpg – a JPG or JPEG is a type of image file format. It is one of the most common formats and 100% supported on web pages. JPG images have the format extension of .jpg. If you have an image that has a lot of differing colours or is of a photograph then the jpg is usually the most suited image format to use. Images can be very large in file size so it is important to compress images for the web.

.gif – a GIF is a type of image file format. A gif image has one standout feature over .jpg and that is that it can have many frames i.e. it is used to animate. Gifs are very popular for displaying meme’s.

It used to be used quite often on the web for images but GIFs dont compress as well as some other image formats such as JPG’s. There are more modern formats that have animation capabilities as well such as WEBP or AV1F. Gifs can be very large in file size so it is important to compress them for the web.

This is an example of what HTML looks like in a web browser.

HTML – HTML or HyperText Markup Language is the code used to make a website online that is interpreted by web browsers. The markup is used primarily to define the structure of the document or page. There is very little styling applied with pure HTML. HTML is used in conjunction with style sheets and scripts to provide design and interactivity to your site. We have a HTML cheat sheet available here.

CSS – CSS or Cascading Style Sheets is the code used to make the styles on your website. It adds colour, size, shape and other visual flair to the page. CSS is used in conjunction with HTML. HTML sets the structure of the page and CSS is what is used to make it look the way it is.

Cross browser test – Each web browser is built by different companies and as such, have their own unique quirks. Although the W3C sets the standard and specifications on how a web page should render, this is not always the case. That is why each website should be tested across all of the browsers that the website will be accessed on.

Cross browser testing can be an intensive task as there are so many different variations that can be tested on. The majority of your users will be using your site on computers running Windows or Mac and tablet/mobile devices on Android and iOS. These devices have browsers such as Chrome, Firefox, Safari, Internet Explorer and Edge.

W3C – W3C is the world wide web consortium that comes up with the rules and standards of the web. The exist to try and maintain order on the open web. All of the major web browsers must try to conform to these rules.

That is why it is important that you only use open source applications that has been independently audited and bug free.

WordPress is open source. The fact that it is open source is one of the reasons why it has gained so much popularity in its time.
