keeping html spaced out

simple question but.. is there any way to keep the spacing in the text editor, so all the code doesn’t get mashed together? eg i’ll i’ll have images like so

...blahblah"</img>

<img src="blahblah...

and next time i go back to it it will all be mashed together

...blahblah"</img><img src="blahblah...

with a whole page this becomes extremely messy and difficult to navigate

thanks
