Hi Claudette,
Start a new document in Expert Mode.
File >> New >> Blank File
Set the dimensions for your text block (width & height) and resolution (normally 72 for web useage) and then set background contents to transparent & click OK
Select the text “T” tool from the tools pallet and click once into the blank file where you want your text; then paste the text from your word document (Ctrl+V)
If necessary select the move tool to re-position and drag the corner handles to re-scale.
Click the green check mark when you are happy and save as PNG to preserve the transparency.
On the top menu click:
File >> Save for Web
From the preset dropdown menu choose PNG24 and ensure transparency is checked, then click Save. Choose a file name and click Save.
