Adding a Webpage with common website elements

vkunge1 Comment

In this lesson we would like to observe how we would create a new web page in WordPress, observe the different presets that are available for us when choosing a layout for that webpage , And eventually choose a blank web page to create our own layout .

We will insert an image to our webpage and wrap text around that image.

We will also observe how to create hyperlinks that link to another web page or an email address or even to a file .

Finally, we will observe how to add this web page to our website using the existing menu navigation system .

Please follow along with the video to create a practice web page on your website. Good luck!

COVID CSEC IT Contingency!

vkungeLeave a comment

Hello Students! ‌ I hope all is well with you and your families.


‌ In order to keep prepared, I’ll be posting some resources and directions via Edmodo (and here on island class). ‌

During COVID Oxford international press has made all Caribbean CSEC books freely available via this link: https://global.oup.com/education/support-learning-anywhere/key-resources-online/?region=international&utm_campaign=learninganywhere&utm_source=umbraco&utm_medium=display&utm_content=support_learning_key_resources&utm_team=int ‌

Just scroll down until you find the section for “Caribbean”.


‌ These books are only available for a limited time. ‌ The book we need to use is available via this link : https://en.calameo.com/read/000777721de16be0f6397?authid=WDfoYvs1wwLH&region=international

Alternatively, you can purchase a pdf copy of Information Technology for CSEC Examinations 3rd Edition here: https://macmillancaribbeanebooks.com/information-technology-for-csce-examinations-3rd-edition-pdf.html ‌

CONTINUING OUR STUDIES

Oxford Information Technology for CSEC Third edition: We continue with pages 138 to 150. ‌

Information Technology for CSCE Examinations 3rd Edition: We continue with pages 161 to 176 ‌ ‌

Please read these pages if you can in order to continue with you studies during this week. ‌ ‌ ‌

As you know, school is currently closed. You are not required to read the information above. However, I feel like the majority of students will at least give it a try as long as your personal situation is comfortable for you to make that attempt.


‌ For those of you who cannot read the notes at this point in time, do not worry!!! ‌

When school officially restarts, we will definitely cover the content. In the meantime, keep safe and keep your mind engaged!
