how to change dimension of cover pic in timeline

hi ..how can i increase the height of cover pic in timeline..

and increase diameter of the profile pic circle..

I wouldn't suggest to change it in the core files, since it will be overwritten during the update, also changing too many files can break auto-update. The correct way to change the feel and look of the site is using custom templates. Please refer to Ocean template - /modules/boonex/ocean/ as an example of custom template.

 thanks for reply ...can't find air template in apps..

will wait for it to launch..

Sorry, I mean "Ocean" template - /modules/boonex/ocean/ 

 thanks ..will check this out ..

/modules/boonex/custom_template/data/template/system/css

Create main.css

@import url(../../../../base/profile/template/css/main.css);

/* profile cover */

.bx-base-pofile-cover {

    position:relative;

    height:22rem;

    -moz-box-sizing: border-box;

    -ms-box-sizing: border-box;

    -webkit-box-sizing: border-box;

    box-sizing: border-box;

}

Then save. Clear CSS and Template Cache. Refresh the profile page, I get...

Warning: file_get_contents(//main.css): failed to open stream: No such file or directory in /home/db_name/public_html/inc/classes/BxDolTemplate.php on line 1390

After second refresh profile page, that Warning disappeared.

If this is wrong. Then, what is the proper path to customise profile cover?

I believe that the correct would be, to create the following file in your custom template:

modules/boonex/custom_template/data/template/bx_persons/css/main.css

with the content like this:

@import url(../../../../../../base/profile/template/css/main.css);
.bx-base-pofile-cover {
    height:22rem;
} 

Thank you, Alex.
