Yeah sure! just select the words by double clicking or selecting it, then you will find a tiny window appear above the selected area, B is for Bold, I is for Italics, U is for underline.
Hi Sushmita
you can do it in tripoto webiste using a system and not in Mobile app.
Just like you bold/italize/underline a word in MS Word u can do it using keyboard.
clt+B = Bold
clt+I= italize
clt+U= underline
To change font size ,select the word and follow the icons H.
Select the the particular section and do a right click it will give you option like bold, italics or you can simply use short cuts like CTRL+B= BOLD. CTRL+I= ITALICS
