If you are copying and pasting content either from another website or from Microsoft Word documents (or similar) please ensure you paste all text content as plain text (there is a tool in the page editor for this)
This process ensures that the default font styles (set in the website stylesheet) are used consistently within the website. If any changes need to be made to the font styling (such as font size, line spacing or font type) this can then be achieved through stylesheet amendments we can make for you, across the board, rather than manually going through the whole website adjusting it on each page.
The page editor does provide simple tools to make text bold, italic or underlined and these are safe to use.
Also try to avoid using the font selection tool within the page editor, as all the fonts needed should already be incorporated in the stylesheet already.
