Try this:
var x ='<p style="font-style: normal; font-variant: normal; line-height: 18px;"><span style="line-height: 34px; font-family: Georgia; font-size: 16px;"><img alt="" src="/Portals/0/Blog%20Images/00aaelevatoredu%20(1024x717).jpg" style="width: 400px; height: 220px; float: left; margin: 5px;" />Whether math problems, an English paper, or a science fair project, more and more teachers are asking students to utilize technology based programs to complete assignments, and students and parents are oftentimes unprepared to meet the new academic requirements. Many times there is an assumption that because kids have grown up with technology, they will automatically know how to use a variety of software programs, but this is often not the case. Kids may be adept at playing video games, using a tablet or cell phone, and working on a computer, but may not have the proficiency in word processing, presentation programs, cloud storage and management, and organizational programs necessary to help them achieve academically. There are many software programs that are crucial for kids to be successful in early elementary school, into college and beyond.</span>'
