If where for your interest: * when using w3c css-validator, this errors shown: * .crp_related .crp_title Property not valid : text-shadow Únicamente 0 puede ser un length. Debe especificarse una unidad detrás de la cifra : 1000 0.1em 0.1em 0.2em .crp_related .crp_title Property not valid : background Función RGB no válida ) .crp_related li:hover .crp_title Property not valid : background Función RGB no válida ) * Thanks.

You must put a unit after your number : 1000 0.1em 0.1em 0.2em 2 .crp_related .crp_title Value Error : background Invalid RGB function ) 3 .crp_related li:hover .crp_title Value Error : background Invalid RGB function ) * 1. says that you must **put unit after numbers**. They explain text-shadow format here: [https://www.w3schools.com/cssref/css3_pr_text-shadow.asp](https://www.w3schools.com/cssref/css3_pr_text-shadow.asp) * 2. and 3. says that rgb and rgba are followind, both together, and **it doesn ´t like rgb** * For example, into 3 you have: * .crp_related li:hover .crp_title{background:rgb(0.2, 0.2, 0.2);background:rgba( 0, 0, 0, 0.8)} * if delete **background:rgb(0.2, 0.2, 0.2)**, no errors into W3c. * Thanks * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [8 years, 8 months ago](https://wordpress.org/support/topic/w3c-css-validator-errors/#post-9571098) * Thanks that helps. I thought the error was with rgba. I’ll fix this in the next version. * Thread Starter [artandscores](https://wordpress.org/support/users/artandscores/) * (@artandscores) * [8 years, 3 months ago](https://wordpress.org/support/topic/w3c-css-validator-errors/#post-9985633) * The validator.w3.org gives several errors: * 1.- Error: CSS: text-shadow: only 0 can be a length. You must put a unit after your number. * text-shadow:1000 .1em .1em .2em * 2.- Error: CSS: background: Invalid RGB function. * background:rgb(0.5, 0.5, 0.5);background:rgba(0, 0, 0, 0.5) * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [8 years, 3 months ago](https://wordpress.org/support/topic/w3c-css-validator-errors/#post-9986479) * Can I check if you were able to fix these on your site by editting the CSS? And if so, what was the revised code? * Thread Starter [artandscores](https://wordpress.org/support/users/artandscores/) * (@artandscores) * [8 years, 3 months ago](https://wordpress.org/support/topic/w3c-css-validator-errors/#post-9995416) * Hi there. I don´t know the better solution to fix this, but are very simple as i said in previous post: * 1. text-shadow:1000 .1em .1em .2em It doesn´t like number 1000. So i think this property is color, something as #100. * 2. background:rgb(0.5, 0.5, 0.5);background:rgba(0, 0, 0, 0.5) It doesn´t like rgb+rgba both together for background (if delete rgb, it fixed -but i dont know what is the right to delete- ). * Thanks. * Plugin Author [Ajay](https://wordpress.org/support/users/ajay/) * (@ajay) * [8 years, 3 months ago](https://wordpress.org/support/topic/w3c-css-validator-errors/#post-10012306) * I just checked it on the CSS site. I think there might be a solution. I’ll look to fix this in the next version. * Thread Starter [artandscores](https://wordpress.org/support/users/artandscores/) * (@artandscores) * [8 years, 3 months ago](https://wordpress.org/support/topic/w3c-css-validator-errors/#post-10013318) * Thank you Viewing 8 replies - 1 through 8 (of 8 total) The topic ‘w3c css-validator errors’ is closed to new replies. * ![](https://ps.w.org/contextual-related-posts/assets/icon-256x256.png?rev=2985705) * [Contextual Related Posts](https://wordpress.org/plugins/contextual-related-posts/) * [Frequently Asked Questions](https://wordpress.org/plugins/contextual-related-posts/#faq) * [Support Threads](https://wordpress.org/support/plugin/contextual-related-posts/) * [Active Topics](https://wordpress.org/support/plugin/contextual-related-posts/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/contextual-related-posts/unresolved/) * [Reviews](https://wordpress.org/support/plugin/contextual-related-posts/reviews/) * 8 replies * 2 participants * Last reply from: [artandscores](https://wordpress.org/support/users/artandscores/) * Last activity: [8 years, 3 months ago](https://wordpress.org/support/topic/w3c-css-validator-errors/#post-10013318) * Status: not resolved
