Tailwind CSS offers various utilities to easily implement these adjustments, such as tracking classes for kerning, shadow color utilities, and smooth transitions to improve the user experience. 64 1 2. 2 [](https://daily.dev/posts/use-css-only-child-instead-of-if-else-logic-wztmo7tvf "Use CSS' `only-child` instead of `if/else` logic") Article RUBYLAND · 2y Use CSS' \`only-child\` instead of \`if/else\` logic Rails developers can leverage powerful CSS features like the \`only-child\` pseudo-class to handle empty states in HTML without writing custom JavaScript or complex logic. By using Tailwind CSS, the \`only-child\` pseudo-class can display a message only when it's the sole element in its parent container. This approach simplifies the code and maintains automatic updates when elements are removed. 45 4 3. 3 [](https://daily.dev/posts/building-a-personal-rag-application-for-pdf-based-question-answering-tx5mahttr "Building a Personal RAG Application for PDF-Based Question Answering") Article RUBYLAND · 2y Building a Personal RAG Application for PDF-Based Question Answering Learn about building a Retrieval-Augmented Generation (RAG) application for PDF-based question answering using LLMs, embedding models, and vector databases.

Using Apollo and GraphQL code generator, you can create hooks for data fetching and pass the resultant data to a view component, making the components easier to test with tools like React Testing Library or render in Storybook. This approach eliminates the need for stubbing the data layer during tests. 16 5. 5 [](https://daily.dev/posts/i-turned-my-website-into-a-jekyll-theme-ylffbnvhk "I Turned My Website into a Jekyll Theme") Article RUBYLAND · 2y I Turned My Website into a Jekyll Theme The author transformed their website into a Jekyll theme to simplify maintenance and enhance functionality.

Feedback and contributions are encouraged. 11 6. 6 [](https://daily.dev/posts/git-deployments-59hsfcfad "Git Deployments") Article RUBYLAND · 2y Git Deployments This post discusses various workflows for deploying changes from a Git repository, with a strong focus on the Rebased Branch Workflow. It compares the common workflows like Trunk, Feature Branch, Gitflow, and Forked, highlighting their downsides like merge conflicts, long-lived branches, and reduced productivity. The Rebased Branch Workflow is presented as a superior alternative, promoting a linear Git history, short-lived feature branches, and automatic deletions post-rebase. CI/CD processes and best practices for managing environments, tags, and cherry-picks are also covered. 11 [See all RUBYLAND archives](/sources/rubyla/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/rubyla/best-of/2024/07#page","url":"https://daily.dev/sources/rubyla/best-of/2024/07","name":"Best RUBYLAND Posts — July 2024","description":"The most upvoted RUBYLAND posts from July 2024, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/rubyla/best-of/2024/07#items","numberOfItems":6,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/ui-design-tips-using-tailwind-css-for-developers-jbguw1fxe","name":"UI Design Tips Using Tailwind CSS for Developers"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/use-css-only-child-instead-of-if-else-logic-wztmo7tvf","name":"Use CSS' `only-child` instead of `if/else` logic"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/building-a-personal-rag-application-for-pdf-based-question-answering-tx5mahttr","name":"Building a Personal RAG Application for PDF-Based Question Answering"},{"@type":"ListItem","position":4,"url":"https://daily.dev/posts/separation-of-data-and-view-layers-in-react-components-dtxmhjcux","name":"Separation of data and view layers in React components"},{"@type":"ListItem","position":5,"url":"https://daily.dev/posts/i-turned-my-website-into-a-jekyll-theme-ylffbnvhk","name":"I Turned My Website into a Jekyll Theme"},{"@type":"ListItem","position":6,"url":"https://daily.dev/posts/git-deployments-59hsfcfad","name":"Git Deployments"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"RUBYLAND","item":"https://daily.dev/sources/rubyla"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/rubyla/best-of"},{"@type":"ListItem","position":5,"name":"July 2024"}]}]} ```
