- The font you have used ('Calibri') is not a web safe font. So, the browser may use a different font.
- the text does not have line-height, so the line spacing will be 'random'
- for different paragraphs use seperate text object. Using empty lines in text to create a margin between text paragraphs usually does not work well in browsers.

Note that these suggestions only apply to absolute layout. When using flexible layout, the layout will automatically be adjusted.
