If you need to have a long piece of text without spaces it may not look good as the browser cannot wrap the text when it gets to the end of the line.
Create a new page from your template and call it longtext.html. Create an empty paragraph element, paste this in and try the page:
Although long words are unlikely you might have a very long url such as http://www.whatalonglinkihaveonmyserver.com/notjusttheservername/butthesefoldersaswell/andlaterthereislotsofgetdata/mypagenameisstupidaswell.php?somevaluesarebestforgotten=true&othervaluesshouldbenamedmoreconisely=true or you might just want to join words together to convey emotion such as if someone in a story walked into a room and saw something shocking and shouted "WhatareyoudoingtherewithmypajamasonandthatrattlesnakeandourremotecontrolpickupnevermindwhatlookslikethreethousandorfourthousandcopiesoftheHTMLstandardsprintedoutandboundinpinkleather?"
Hopefully your browser coped with the long URL by breaking it at a slash or other symbol but the text should look pretty bad.
To avoid this you place wbr elements between each place you are happy to have the text wrapped. In this case that would be between every word in the exclamation. The browser will not wrap it at every possible break but will use the ones it needs. You could also try to keep the url easier to follow by encouraging breaks at suitable points. The code might look like this so delete the existing text and replace it with this:
Although long words are unlikely you might have a very long url such as http://www.whatalonglinkihaveonmyserver.com/<wbr>notjusttheservername/<wbr>butthesefoldersaswell/<wbr>andlaterthereislotsofgetdata/<wbr>mypagenameisstupidaswell.php<wbr>?somevaluesarebestforgotten=true<wbr>&othervaluesshouldbenamedmoreconisely=true or you might just want to join words together to convey emotion such as if someone in a story walked into a room and saw something shocking and shouted "What<wbr>are<wbr>you<wbr>doing<wbr>there<wbr>with<wbr>my<wbr>pajamas<wbr>on<wbr>and<wbr>that<wbr>rattlesnake<wbr>and<wbr>our<wbr>remote<wbr>control<wbr>pickup<wbr>never<wbr>mind<wbr>what<wbr>looks<wbr>like<wbr>three<wbr>thousand<wbr>or<wbr>four<wbr>thousand<wbr>copies<wbr>of<wbr>the<wbr>HTML<wbr>standards<wbr>printed<wbr>out<wbr>and<wbr>bound<wbr>in<wbr>pink<wbr>leather?"
Try it. It may not be perfect but should be slightly better.
