Short, simple explanation you can tell the group:
Inline style = putting CSS directly on an element, e.g. <p style="color:red">…
Why inline styles are a bad idea for a group project
- Hard to maintain: if you want to change a color or font later you must edit every element that has inline styles.
- Repetition: the same rules get copied many times, making the file bigger and messy.
- Inconsistent look: easy for different people to apply slightly different inline styles and break consistency.
- Poor scalability: adding pages or features becomes a pain because styles aren’t centralized.
- Harder to collaborate: merging and reviewing code is simpler when styles are in one CSS file.
- Limited features: media queries, pseudo-classes (:hover), and many advanced selectors can’t be applied via inline style.
- Specificity problems: inline styles override many stylesheet rules, making debugging and future changes harder.
- Worse performance across pages: external CSS files can be cached by the browser; inline styles cannot.
What to do instead (very simple)
1. Create a stylesheet (styles.css).
2. Move repeated rules into classes or selectors:
- Before: <p style="color:red; font-weight:bold">Result</p>
- After: <p class="alert">Result</p> and in styles.css:
.alert { color: red; font-weight: bold; }
3. Link the stylesheet in <head>: <link rel="stylesheet" href="styles.css">
How to say it nicely to the group
“Nice first draft! To make the site easier to update and keep consistent, can we move the inline styles into a single CSS file and use classes? I can help refactor it if you want.”
Want, I can refactor one sample page into external CSS and show before/after.
