I’ve downloaded your logos and investigated as follows:
@trendyrevels, your .jpg is exactly 250px x 100px. Customizr has a tickbox to limit size to that dimension, so if you untick the box it still displays at that size. What size do you want? Can you produce a larger .jpg using a picture editor (eg Photoshop)?
@mindovermattersound, your .png is 899px x 125px. What size do you want?
The actual code generated is allowing about c25% for the brand/logo & c75% for the navbar. (It’s actually 23.0769% as set by Twitter Bootstrap grids).
If you try the following:
.navbar-wrapper .brand {width:23%; float:left;}
.navbar-wrapper .navbar {width:77%; float:right}
By increasing the .brand width>23% forces a bigger logo (depending on width of jpg/png, but results in an extra line for the .navbar. By playing with these 2 widths, I can work different layouts.
Making both width:100% moves the logo to it’s own line and centers it, with a full-width navbar beneath.
You may need to adjust margin/padding.
Hope this works for you.
