Buttons are not aligned with the searchbox

Hi,

I recently installed the AnsPress Plugin , everything is working fine except that the buttons “Ask Question” , “Category”and “Sort by” are not alligned with the Search box. Instead they they are appearing under it. You can check the and press page on my blog here http://www.theengineeringprojects.com/ask-question

It is also shown in the below image, I have circled it as well. Kindly let me know how to resolve this issue. Btw really great plugin.

Thanks.
