These are applied via CSS media queries. Most likely on your site you have only worked on styling for desktops and that’s why it only appears as you like it there. Mobile styling has not been affected because the theme’s default media queries have not been altered. Take a look at this tutorial which explains media queries [https://www.webucator.com/tutorial/advanced-css/media-queries.cfm](https://www.webucator.com/tutorial/advanced-css/media-queries.cfm) for more information. Also MDN has a pretty extensive coverage of media query usage [https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries](https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries) * Thread Starter [neeville](https://wordpress.org/support/users/neeville/) * (@neeville) * [7 years, 5 months ago](https://wordpress.org/support/topic/olsen-theme-crashes/#post-11076993) * hi, again thanks for replying. Like i said earlier the css use was functioning properly on both mobile and desktop version till i decided to upload a logo. at first the logo uploaded without issues then i later decided to to increaase the font size of the logo via css. i did not succeed in setting the logo font to my test but i decided to let it be. Then about 2 days later i realise that the theme was back to default. the plug ins, widgets etc are still in place but css code are not working. The desktop view still looks like nothing ever happen though. please help as i have been searching for a solution all this while but nothing is working. thanks * [Nik](https://wordpress.org/support/users/nvourva/) * (@nvourva) * [7 years, 5 months ago](https://wordpress.org/support/topic/olsen-theme-crashes/#post-11078499) * I took a look at your [custom CSS](https://spicegadget.com/?display_custom_css=css&ver=5.0.3) there are some linting errors and perhaps they are the cause of the issues you are facing. * For example, you are starting a media query in line 27 but you never end it, instead you start a new one in line 88. This means that the second media query won’t ever fire. Similarly there are linting errors at the end of your custom stylesheet. * You can use an online linter such as [this one](http://csslint.net/) or if you are using a code/text editor that comes with CSS linting support, use that to fix these issues. Then you should be ok.
