Do My HTML & CSS Homework
HTML and CSS is the one assignment language with no assert and no return value. The grader opens your page, resizes it, runs it through the W3C validator, and compares the pixels to a reference. A front-end developer builds a layout that survives a window resize and validates with zero errors.

What we cover
The full HTML & CSS toolchain your course grades on
There is no test runner here. The grader runs your markup through the W3C Markup Validator, audits it with Lighthouse and axe, and resizes the window in DevTools. We cover every piece of that chain, from the box model to WCAG 2.1 AA contrast.
Whichever stack your brief names, the developer hand-codes it. Vanilla Flexbox and Grid for a from-scratch layout. Bootstrap when the rubric wants the 12-column grid with col-md-* tiers. Sass with variables and nesting when the course teaches a preprocessor. We do not template one approach onto a brief that asks for another.
The layout engines are where most marks live, so we choose deliberately. Flexbox for a one-dimensional row of cards. Grid with fr and minmax() for a two-dimensional page. That choice is the difference between a layout that holds at 320px and one that bursts its container the moment the content grows.

Four HTML & CSS assignments we build end to end
An assignment is the graded artifact you deploy and submit, not a one-line fix. These four cover most coursework, from a pixel-match clone to a Figma conversion. Each one ships validated and checked at the breakpoints your brief names.
Pixel-match clone of a real site
Re-create the front end of an existing page from a screenshot or a live URL. The CS50W Project 0 "Search" Google clone is the canonical brief: a Search, Image Search, and Advanced Search trio with a centered rounded search bar, an "I'm Feeling Lucky" button, and CSS that matches Google's own aesthetics. Graded on visual fidelity to the reference, not on any backend logic. We hand-code the spacing, the type scale, and the color tokens to the comp, then check it in the browser side by side with the reference until the pixels line up.
Responsive multi-breakpoint layout
Build a page that reflows across mobile, tablet, and desktop using Flexbox or CSS Grid plus @media queries, or Bootstrap's grid if the rubric names it. No horizontal scroll at 320px, and content that wraps instead of overflowing. Graded by resizing the viewport at the breakpoints in your brief, usually 320, 768, and 1024 px. We build mobile-first, set box-sizing: border-box as a reset, and use fr units with minmax() so a track flexes instead of bursting its container.
Personal portfolio or résumé site
A multi-page semantic-HTML site with a header, nav, main, and footer, an external stylesheet, working navigation, and a contact form with label and for pairs. Deployed to GitHub Pages or Netlify with the live URL submitted. Graded on semantic structure, responsiveness, and that it validates clean. We wire the navigation, label every field for the accessibility audit, and deploy the static build so the link you submit is the link the grader opens.
Figma-to-HTML/CSS conversion
Translate a supplied Figma mockup into hand-coded, accessible markup, often Sass-based and BEM-named, matching the comp's spacing, type scale, and color tokens. Graded on fidelity to the design plus a W3C validation and WCAG accessibility pass. We read the spacing and type tokens straight off the design, name classes with BEM so the cascade stays predictable, and compile the Sass to a clean stylesheet that the validator accepts with zero errors.
HTML & CSS assignment help
Help scoped to how an HTML & CSS assignment is actually scored
HTML and CSS assignment help here means matching the four grading checks, not guessing at them. Submissions are scored by visual inspection against a reference at named breakpoints, by the W3C Markup and CSS Validators, by Lighthouse, axe, or WAVE accessibility audits, and by a deploy-and-open of the live GitHub Pages or Netlify URL.
So the help covers four layers. The visual match to the comp. The clean validation pass. The accessibility score, with alt text, label pairs, and 4.5:1 contrast. And the working deploy, because a portfolio brief that does not load at its live URL loses marks before anyone reads the code.
Some courses add a structural autograder on top. CodeGrade or the webtech-network grader checks that required elements are present, that the named selectors are used, and that there are no inline styles. We build to those structural rules too, so the markup passes the machine check and the human one.
HTML & CSS homework help
The six layout bugs we fix every week
Weekly homework breaks in predictable ways, and almost always in the layout rather than the syntax. These six account for most of the broken submissions we see. Each one has a known fix and a comment so you can explain it.
A div is too wide and breaks the layout
Adding padding or a border to a width:100% element pushes it past its container, because the default content-box model adds them outside the declared width. The fix is one reset: set box-sizing: border-box on * so a 200px width with 20px padding still renders at 200px, not 240px. We add the reset and explain the box-model math in a comment.
A style refuses to apply and !important is creeping in
A more-specific selector, usually an id or a longer chain, outweighs your rule, so the page ignores it and students reach for !important and make it worse. The fix is to read the cascade weight (inline 1000, id 100, class 10, element 1) and either lower the winning selector or raise yours by one class. We resolve the conflict without !important, which most hand-code rubrics penalize.
A vertical gap is missing because margins collapsed
Adjacent or parent-and-first-child margins merge to the larger of the two instead of summing, so the space you set never appears. The fix is to separate with padding or a border, or to use a Flex or Grid container with gap, because margins do not collapse inside flex and grid. We pick the mechanism your layout already uses so the rest of the page does not shift.
The desktop layout ships to mobile tiny and zoomed out
The viewport meta tag is missing or there are no breakpoints, so the phone renders the full desktop width scaled down. The fix is the tag plus mobile-first @media queries. We add the tag, set the breakpoints from your brief, and verify there is no horizontal scroll at 320px.
Flexbox or Grid does nothing on the container
justify-content or grid-template-columns has no effect because the parent never got display:flex or display:grid, or a column collapses because content exceeds a fixed track. The fix is to declare the container display mode and use minmax() and fr for flexible tracks instead of hard pixel widths. We set the display mode first, then size the tracks so content wraps instead of overflowing.
z-index is ignored or an absolute element floats off
z-index does nothing on a static element, or an absolutely positioned child anchors to the wrong ancestor and drifts across the page. The fix is a positioning context: give the element position relative, absolute, or fixed, and set position on the intended containing block so the child anchors where you meant. We trace the stacking context in DevTools and pin the anchor.
/* before: div overflows at 320px, 3 W3C errors, contrast 3.1:1 */
/* after: box-sizing fixed, validates clean, contrast 4.7:1 AA */
.card { width: 200px; padding: 20px; } /* renders 240px, overflows */
* { box-sizing: border-box; } .card { width: 200px; padding: 20px; } /* 200px ✓ */
/* "I could finally explain why I used Grid instead of Flexbox in my viva." */
/* - web design student, 2026 */What you get
A delivery you can render, defend, and submit
Zero-error W3C validation
The markup passes the W3C Markup Validator and the styles pass the CSS Validator with no errors, because a clean validation pass is a scored line on most rubrics and the first thing a grader checks.
A layout checked at your breakpoints
We resize the page at the breakpoints in your brief, usually 320, 768, and 1024 px, confirm there is no horizontal scroll, and screenshot each one so you can see the match before you submit.
Semantic, accessible, commented code
A header, nav, main, and footer structure, alt text and label pairs for the accessibility audit, 4.5:1 contrast, and a comment on each non-obvious rule so you can read it in a viva.
A live URL and viva answers
A GitHub Pages or Netlify deploy with the live link, plus two or three questions a grader asks, like why Grid here and not Flexbox, with answers you can defend.

Help with HTML & CSS assignment
Course-specific help, matched to the validator and the audit
HTML and CSS show up in the first weeks of every web course and in standalone design courses, never as a CS-theory unit. We honor each one. Harvard CS50W opens with the HTML and CSS week and Project 0 "Search", the Google clone. Stanford CS193X begins with layout and rendering before any JavaScript. UC Berkeley Extension runs a hand-coded Web Design with HTML5 and CSS3 track from wireframes to production.
The grading format matters as much as the markup. Accessibility and standards units fold a WCAG 2.1 AA and W3C validation requirement into the rubric: alt text, contrast, semantic structure, and keyboard nav. Hand-code-only briefs ban Wix and Dreamweaver and penalize !important spam and non-semantic div soup. We build to whichever convention your course sets, then verify against it before delivery. Plagiarism checks with MOSS and Turnitin pass because every line is hand-written fresh for your brief.
Pricing
One fixed price per assignment, from $20
Priced by complexity, not by a meter. A single responsive page sits at the low end. A multi-page portfolio with a Sass build and a deploy sits at the top. You see the full number before you pay, and there are no rush fees.

Questions, answered
Straight answers about validation, responsiveness, frameworks, and the layout bugs that cost rubric points.
Will my page validate with zero errors on the W3C validator? +
Yes. We run your markup through the W3C Markup Validation Service and your styles through the W3C CSS Validator, then deliver zero-error, semantic HTML5. Zero-error validation is often a scored rubric line, so we treat it as a hard delivery gate, not a nice-to-have.
Will it be responsive on mobile, tablet, and desktop? +
Yes. We build mobile-first with @media queries, or Bootstrap’s grid when the rubric names it, and verify the layout at your stated breakpoints, usually 320, 768, and 1024 px. There is no horizontal scroll at 320px and content wraps instead of overflowing.
Can you make it pixel-match the reference design or Figma mockup? +
Yes. We hand-code to the comp’s spacing, type scale, and color tokens, then check it in the browser against your reference until the pixels line up, the same way the CS50W Project 0 Google clone is graded on visual fidelity rather than logic.
Do you use Flexbox or CSS Grid, or whatever my rubric requires? +
Whichever your brief states. Flexbox for one-dimensional rows, CSS Grid for two-dimensional layouts, Bootstrap or plain CSS if the rubric mandates it. We also write the viva answer for why each was used, so you can defend the choice.
My styles will not apply and I have a specificity war. Can you fix it? +
Yes. That is a cascade and specificity problem. We resolve it by adjusting selector weight, reading the inline-100-10-1 hierarchy, instead of spamming !important, which most hand-code rubrics penalize and graders flag.
Will it pass the WCAG accessibility and Lighthouse audit? +
Yes. Alt text, label and for pairs, 4.5:1 contrast on normal text, semantic structure, and correct heading order, so the page clears axe, WAVE, and the Lighthouse accessibility category. We check the audit before delivery, not after you submit.
Can you deploy it to GitHub Pages or Netlify and give me the live link? +
Yes. We deploy the static site to your host of choice, GitHub Pages or Netlify, and hand over the live URL plus the source so you can submit both. Portfolio and résumé briefs that ask for a deployed link are a normal part of the work.
Can you write it in Sass/SCSS or with Bootstrap if that is required? +
Yes. Sass with variables, nesting, mixins, and partials compiled to clean CSS, or Bootstrap’s 12-column grid and components, matched to whatever your course assigns. We compile through Vite or Dart Sass so the stylesheet that ships is the one the validator reads.
