Tumblr offers more than 50 themes in the "Grid" category, many of them premium themes that you must purchase before use. After you've installed a free or premium theme on Tumblr, you can edit the source code on your blog's customization page. To change the number of columns in a grid theme, you must know how to read and modify CSS stylesheets.
Modifying Various Themes
Open the customization page for your Tumblr blog and click the "Edit HTML" link to open up the source code for your theme. Every theme developer has a different style, and there's no uniform method for changing the column aspect of a grid theme. For instance, the "Astronaut" grid theme has a class called "#container .box". Changing the width in this class from the default "225px" to "150px" takes the theme from three columns to four. Some themes, like "Syndex, " don't require you to modify the CSS at all; the theme options allow you to set pixel width for post types, which changes how many display side-by-side. Not all grid themes can be easily modified. For instance, the "Club Monaco Theme" uses an externally linked stylesheet which you cannot edit.
Reverting to the Original Theme
If you decide that you don't like your modified version of your theme, you can go back to the original version. Open the "Browse Themes" section of the customization page. Select the original theme, click "Use" and save the changes to your blog.startup disk full mac fix fintech montreal 1 year development development news developmental theory in criminology popular quotes 2017 about life service entrepreneurs financial technology partners interview people on vacation cities in pennsylvania that start with p tide fintech entrepreneurship ideas koa to vegas entrepreneur quotes motivational entrepreneurship skills development small entrepreneurs spa treatments my week vacation startup nation book pdf product entrepreneurs appropriate technology startup grind dayton power motion motivation letter for job application app motion m t development small business ideas for small towns in india development academy vacations to go reviews atom fintech 2 year development expansion development's development book vacation for 2 developmental pediatrician nj entrepreneur magazine customer service the entrepreneurs video entrepreneurship skills training three vacation how to remove startup repair virus york vacation cities in pennsylvania that start with m vacation free vacation states story of entrepreneurs hotel entrepreneurs city vacation entrepreneurs source tools for financial success worksheet cities in north carolina by population what a vacation what is city development vacation women fintech analyst fintech companies in atlanta news in motion what is motor motion times fintech journalists work development amazon web services out of city startup pro development business motion job financial technology pdf state map of ohio with cities pc startup cities in arizona that start with s developmental milestones 4 months vacations changes vinyl top city fintech advisory job startups working at fintech alternative funding sources for christian startup development through the lifespan 6th edition business for development google startup city first vinod khosla development film how to meet pitch air motion types of motivation in psychology pdf development of team based startup how to entrepreneur cities xl women motion impact investing where is this city how to startup cities skylines 2 vacation blog startup india ideas fintech board how to find investors online entrepreneur definition life motor startup start startup grind promo code development man vacation in the kate spade quotes on wood google startup
