Align text to the left in Gallery pages

Hello, 

I am currently making a Gallary. I had chosen to show Title under each image but unfortunately the alignment is to the centre of each image though I would like it to be to the left. I have tried the custom css:

.page-text-wrapper.clearfix * {
    text-align: left;
}

but I cant seem to make it work. Nothing changes? Am I inputting it in wrong? 

Also is it possible to have two lines for a title? 

Hi,
